How to Use a Python Library in Java via Its API

Combining different programming languages in a single project can be very powerful. One useful combination is using Python libraries in a Java program. This lets you take advantage of Python’s many tools, like those for data analysis or machine learning, while still using Java’s strength in building large, reliable applications. This guide will show you how to use a Python library in Java through an API.

Why Combine Python and Java?

Python is known for being easy to use and having many libraries that can help with various tasks, like data processing or machine learning. On the other hand, Java is a popular choice for big projects because it’s fast and reliable. By combining the two, you can use Python’s great tools in a Java program, getting the best of both worlds.

One way to make Python and Java work together is by using an API. An API, or Application Programming Interface, is like a bridge that lets different software pieces talk to each other. In this case, the API lets your Java program use Python libraries.

Step 1: Choosing the Right Tools

To start, you need the right tools to connect Python and Java. Here are a few options:

Jython: Jython is a version of Python that runs on the Java platform. It allows you to use Python code directly in Java. However, it doesn’t support the latest Python versions, and it may not be as fast as other options.

Py4J: Py4J allows Java programs to run Python code and share data between the two languages. It’s a flexible and popular choice for this kind of integration.

Jep (Java Embedded Python): Jep embeds a Python interpreter in Java applications, allowing you to run Python code from Java. It’s designed to be fast, making it a good choice for performance-sensitive tasks.

Step 2: Setting Up Your Environment

We’ll focus on using Py4J to call a Python library from Java. Here’s how to set up your environment:

Install Python: First, make sure Python is installed on your computer. You can download it from the official Python website.

Install Py4J: Next, install Py4J by running this command in your terminal:

3. Set Up a Java Project: Create a new Java project using your preferred IDE, like IntelliJ IDEA or Eclipse. Add the Py4J library to your Java project. You can download it from the Py4J website or add it using a build tool like Maven or Gradle.

Step 3: Writing the Python Code

Let’s say you want to use a Python library called NumPy to calculate the square of a number. First, create a Python script that does this. Here’s an example:

Save this script as my_script.py in your working directory.

Step 4: Writing the Java Code

Now, write the Java code to call this Python script using Py4J. Here’s an example:

import py4j.GatewayServer;

public class PythonCaller {

    public static void main(String[] args) {

        GatewayServer gatewayServer = new GatewayServer();

        gatewayServer.start();

        System.out.println("Gateway Server Started");

        try {

            Process process = Runtime.getRuntime().exec("python my_script.py");

            BufferedReader in = new BufferedReader(new InputStreamReader(process.getInputStream()));

            String result;

            while ((result = in.readLine()) != null) {

                System.out.println(result);

            }

            in.close();

        } catch (IOException e) {

            e.printStackTrace();

        }

    }

}

This Java code starts a Py4J gateway server to connect with Python. It then runs the Python script using the Runtime.exec() method and prints the result.

Step 5: Running and Testing

After setting up your Python and Java code, you can run your Java program. Here’s what will happen:

The Java program starts the Py4J gateway server.

The Java program runs the Python script.

The result from the Python script is printed out by the Java program.

You can test this setup by trying different Python libraries, like pandas for data analysis or scikit-learn for machine learning, and see how they work with your Java program.

Step 6: Sharing Data Between Java and Python

Often, you’ll want to pass data back and forth between Java and Python. Py4J makes this easy. For example, you can send a list of numbers from Java to Python, have Python square them using NumPy, and then return the squared numbers to Java.

Python Script (my_script.py):

Java Code:

import py4j.GatewayServer;

import py4j.Py4JNetworkException;

import java.util.Arrays;

import java.util.List;

public class PythonCaller {

    public static void main(String[] args) {

        GatewayServer gatewayServer = new GatewayServer(new PythonCaller());

        gatewayServer.start();

        try {

            List<Integer> numbers = Arrays.asList(1, 2, 3, 4, 5);

            Object[] results = gatewayServer.getPythonServerEntryPoint(new Class[] {}).calculate_squares(numbers);

            System.out.println("Squared numbers: " + Arrays.toString(results));

        } catch (Py4JNetworkException e) {

            e.printStackTrace();

        }

    }

}

Best Practices to Keep in Mind

When using Python in a Java program, there are a few things to remember:

Error Handling: Make sure your Java code can handle any errors that might come up when running Python code. This will help keep your Java program stable.

Performance: Running Python code from Java can slow things down, especially if you’re working with large amounts of data. Test your setup to make sure it’s fast enough for your needs.

Security: Be careful when running external scripts, especially if they use user input. Make sure inputs are safe and won’t cause security issues.

Documentation: Keep good notes on how your Python and Java code work together. This will make it easier to update or fix your code later on.

Conclusion

Using Python libraries in a Java program can make your projects much more powerful. By following these steps, you can set up a system where Java and Python work together smoothly. Whether you’re doing data analysis, machine learning, or any other task, combining Python and Java can help you get more done with your code.

JUNIT TESTING by H2kinfosys

Junit testing is a type of unit testing which is implemented in java to accelerate the programming speed and increase the quality of code. This application is integrated with eclipse, Ant, Maven. The important features of Junit testing are:

Fixtures

Text suits

Test Runners

Junit classes

Fixtures:

Fixture is a complete fixed state of set of objects used as a baseline for running tests. The main purpose of test fixtures, is to ensure that there is a well known fixed environment in which we check if the results are repeatable. It has two methods

A setup () method which runs before the test invocation.

A teardown () method which runs after the test method.

Test Suites:

A test suite groups a few test cases and runs them together. The both @Runwith and @suite annotation in Junit are used to run the suite test.

Test Runners:

It is simply used for executing test cases.

Junit classes:

There are some important classes of Junit

Assert: it contains a group of assert methods.

Test case: it may contain a test case which will define the fixture to perform multiple tests.

Test Result: it contains the method which collects the test result of executing test case.

The Junit provides tool for execution of test cases. Junit core classes are used to run these test cases. A method called runclasses is used, which provides org.Junit.runner.Junitcore is used to run the several test classes. The return type of this method is the Result object (org.Junit.runner.Result) which access information about tests.

What is the necessity of Junit Testing in java?

We need Junit testing for following:

Mainly, it finds the bugs early in the code and makes the code reliable.

Junit is useful for developers who are in test-driven environment.

Shopping List

What you need to develop Android apps with Eclipse IDE: -An Android device (or emulator) -Android SDK installed -Eclipse IDE installed -Android development tools installed (JDK and Android SDK Tools) -An internet connection

Getting Started with Android Studio

If you’re new to Android development and don’t have a development environment set up yet, you’re in luck! In this blog post, we’ll show you how to get started with the Eclipse IDE and use its open source tools to develop Android apps.

This guide is for developers who are familiar with either the Java programming language or the Eclipse IDE. If you’re new to Android development, we suggest reading our beginner’s guide first.

Once you have your development environment set up, first install the Android Studio plug-in. This will give you access to the Android SDK and all the necessary tools. Next, create a new project in Eclipse by selecting File > New > Project… from the main menu. Under Projects on the left-hand side, select Android > New Android Project. Enter a project name (for example, “MyFirstAndroidApp”) and click Next. On the next screen, select a destination for your project files (for example, your desktop) and click Finish.

Once your project has been created, open it in Android Studio by selecting File > Open… from the main menu. You’ll see a window with several tabs: Project Structure, Build Paths and Properties, Main Activity,

Android Manifest File

Android app development is a great way to learn new programming skills and have some fun at the same time. A lot of people use open source tools such as Eclipse IDE to develop their apps. This blog will show you how to develop Android apps with Eclipse, using a manifest file as your guide. This manifest file tells the Android system what your app does and what permissions it needs. You’ll also learn how to use the Android SDK, which includes tools for creating and testing apps.

Compiling and Running the App

If you’re looking to develop Android apps using open source tools, the Eclipse IDE is a great option. In this article, we’ll show you how to compile and run an app using the Eclipse IDE.

Before getting started, make sure you have:

• An Android device or emulator installed and set up • The Android SDK installed (download here) • The Eclipse IDE (download here) • A Java Development Kit (JDK) installed (download here) • A USB cable to connect your device or emulator to your computer • An internet connection

To start, open the Eclipse IDE and create a new project by clicking on the New button in the Project toolbar. Select Android as the Platform and enter App for the project name. Click on the Next button.

Now that we’ve created our project, we need to set up some properties for our project. In the Properties dialog box, select the General tab and configure the following:

Configure your target device(s): We’ll be compiling and running our app on an Android device or emulator, so select Device or Emulator from the Target dropdown list. If you ‘re using Eclipse for the first time, you should see an unknown device/emulator type. If so, select it from the list and click on Next.Configure your build: We’ll be building our app in debug mode by default. Enabling this means that we’ll be running our app in a custom build process (we won’t be using the Android SDK’s default one).Select Debug(TM) and press OK to confirm that your target is set correctly.Configure your project name and package name: The project name is what appears in Eclipse’s Project view; it appears at the top of your main class file’s declaration.

This can be up to 27 characters long. The package name is what appears on every application icon or launcher icon. It is 10 characters long.In the screenshot above, you can see that the package name is trivial and doesn’t contain any file names. It’s something like my_package_name . This can be changed by editing the manifest file (see below).The project name needs to be unique across all applications on your device or emulator; it is used to determine which application should launch when you click on a launcher icon.

The project name cannot be repeated in the same package as another application; if your app has the same package name as another, it’s likely that they’ll both appear in a list of apps on a launcher icon.The Package Name must be unique across all applications on your device or emulator. If you have multiple version of the same app installed on a device (e.g., two versions of the “Google Maps”) then you need to maintain an additional name for each version, such as my_google_maps_2.apk. You can also have a different package name for each individual application; this is useful if you want to allow multiple users to install your app on the same phone with separate data and preferences.When installing your application, you will be asked whether it appears in the launcher list (more details below).If you aren’t sure about what these are, don’t worry about them for now; Android will prompt for them when needed during development. Note that some values are required: android:name and android:version . Feel free to try other values, but be sure to leave them out if you decide they are needed.

Android Package Name In order to store your application’s data and preferences in the phone, you will need an Android package name. The package name is used by the system when it needs to load your app from the phone. For example, when taking a picture of a particular location, the system will find your photo-taking app in its launcher list, then use that package name to look for your preferences and data about that location stored in your app’s preference file or database. You can edit this value later using Eclipse’s Project Properties view (under “Android Manifest”).

Package names can contain any characters except . and _ . However, don’t put spaces in the name, it could cause problems.

Your app’s package name must match the following format: com.example.appname . This can be a simple app with no activities or other subfolders that differ from this example, but ideally your app will have at least one activity (for managing other apps), and one or more subfolders for the various data you’ll need to manage. The exact file structure will depend on how you want users to access your app’s functionality and data. You should add enough information about your app’s layout so that a user can easily find what they want in the folder hierarchy when they launch your app (e.g., “Photos” or “Favorites”).

The name of your app must match the following format:.

The exact file structure will depend on how you want users to access your app’s functionality and data.

This is a basic activity that will let users add movies to their library. You can do whatever you want in each method, including creating the AddMovieView . If you need to use any third-party libraries or code snippets, make sure that they are available under your package name ( com.example ) and not in the system library. If your app supports multiple databases, you will have to include them in the AndroidManifest.xml file.For this example, we’re just going to create a simple movie database; if you want to learn more about developing an app with data storage, make sure to read the tutorial on Android Studio’s Data Management and Storage topic.When you run this application (or any other activity), an Add Movie dialog will appear with a list of movies found on Google Play Movies, Netflix and YouTube. The user can add movies by selecting them from this list or typing their own title in the first text field.The second text field is for entering details about the movie (e.g., its rating). When a user selects a movie from the provided list, that movie’s details are displayed in the Edit Movie dialog.We’ve defined two activities for this app, an onCreate() method for each (enter code below to show these onCreate() methods).Here we create a new activity called AddMovieActivity and start it running:Once you have a new instance of your activity running, you can use it to begin interacting with the user. In this case, our AddMovieActivity is a simple text input screen where we’ll enter the title of our movie.If you run this application now, you should see something similar to the screenshot below:Now that we’ve created our activity and started it running, let’s start working on the corresponding model class…

The Maven Quick Start course is designed to cut academic theory to just the key concepts and focus on basics tasks in Maven in order to be productive quickly. The lessons and examples provided are delivered in a step-by-step, detailed way to ensure mastery of the skills and topics covered. Course Outline Introduction walks through the course goals, approach and the core concepts of Maven. After that, we breeze through installation of all required tools in the Quick Installation section. The full step-by-step installation process is available in the Bonus sections. In Setup and Getting Help, we cover how to ask for help in Maven. We also download the course working files on GitHub.With the formalities out of the way, we dive into a Maven Quick Start By Example, walking the foundational aspects of Maven using a sample application.After the basics are covered, we explore Maven Plugins in more detail by customizing our project using them.One of the key aspects of Maven, is how it handles Dependencies. We go deeper by adding dependencies from Maven Central and explore the role of scopes with dependencies in Maven. Then we improve our project by Unit Testing -- where we add JUnit tests, deal with (and avoid) testing failures. Finally, the last section of the main part of this course is dedicated to running Maven within Eclipse using the M2Eclipse plugin.Finally, we will look at Using Archetypes to jump start Maven projects by using a template system. During the entire course, we get into a habit of saving our changes periodically using Git source control. Course Features Presentations provide audio/video training of conceptual ideas. Since few like slide-ware presentations, slide-presentations are kept to a minimum. Over 2 hours of Screencasts provide a video of the instructor's computer system with any actions, commands, or screens displayed and narrated. Project files and examples are all available on GitHub.

Jitsi Meet lets you stay in touch with all your teams, be they family, friends, or colleagues. Instant video conferences, efficiently adapting to your scale. Unlimited users: There are no.

If you want to run Jitsi on your own desktop or server, you can download Jitsi Desktop, Jitsi Meet and all Jitsi related projects below. Use the stable builds for more consistent behavior. Latest nightlies are also quite usable and contain all our latest and greatest additions.

Download Jitsi Meet for iOS to jitsi Meet lets you stay in touch with all your teams, be they family, friends, or colleagues. Compatible with iPhone, iPad, and iPod touch.

For over a decade, the App Store has proved to be a safe and trusted place to discover and download apps. But the App Store is more than just a storefront — it’s an innovative destination focused on bringing you amazing experiences.

But what if I want to share my iPhone/iPad screen to the Jitsi meeting. Pc — Iphone/iPad perfect but iPhone/iPad —- pc doesn’t work. Zoom And teams has the option for example.

Distance doesn’t matter

This video conferencing software differs from its larger competitors by being open-sourced. It provides no limits upon what you can do with it, making it stand out among the other options available.

No bars to tie you

Jitsi Meet provides an innovative way to build online connections to people.

Jitsi Meet’s largest competitor is Zoom. It exploded into popularity, overcoming Skype, by offering high-quality connections for large groups. While Meet suffers from quality issues when it has to host large groups, it's open source and the user doesn’t need to pay.

One thing Jitsi Meet has that is superior to Zoom, is that you don’t need to download anything to start using it. Unfortunately, it's more complicated to use and doesn't provide the video conference tools that are needed to run a big group.

Since this app aims more for simplicity, it lacks many features it could have without taking away from the basic design. Finally, loading it can be troublesome, but once it gets going, it does a good job.

Where can you run this program?

It requires iOS 11.0 and watchOS 4.0 and onwards.

Current releases of Eclipse require Java 8 or newer. If you are using Eclipse to do Java development, or are on macOS, install a JDK. In all cases, 64-bit Eclipse requires a 64-bit JVM, and a 32-bit Eclipse requires a 32-bit JVM. Additionally, how do I download JDK for Eclipse? Current releases of Eclipse require Java 8 or newer. If you are using Eclipse to do Java development, or are on macOS, install a JDK. In all cases, 64-bit Eclipse requires a 64-bit JVM, and a 32-bit Eclipse requires a 32-bit JVM. Where does eclipse get installed? The essential tools for any Java developer, including a Java IDE, a CVS client, Git client, XML Editor, Mylyn, Maven integration and WindowBuilder. Download jdk for eclipse. In Windows: From the Eclipse main menu, choose Window→Preferences. On the Mac: From the. It's probably best to configure a JDK for programming in Eclipse. Is not that a JRE won't run your program, because it will (it includes the JVM executable anyway). The thing is, using the JDK will give you access to the JDK source code (and javadoc) which is more likely what you want.

Is there a better alternative?

Yes, Zoom is superior to Jitsi. It has a host of features but can also be used for basic calls. Livestorm is a much more expensive option, but it is perfect for larger companies that need to have large conference calls.

Our take

Jitsi Meet suffers from problems that keep it from succeeding in the call hosting arena. Its main saving grace is the open source nature of the program and the free-to-call model.

Should you download it?

No, it does not have the quality necessary to compete in the market.

Wrong. You need to drop JAR in /WEB-INF/lib folder. You don't need to create any additional folders.

3: properties of project->build path->add JAR and selected the JAR above.

Unnecessary. Undo it all to avoid possible conflicts.

4: I still get java.sql.SQLException: No suitable driver found for jdbc:mysql//localhost:3306/mysql

This exception can have 2 causes:

JDBC driver is not in runtime classpath. This is to be solved by doing 2) the right way.

JDBC URL is not recognized by any of the loaded JDBC drivers. Indeed, the JDBC URL is wrong, there should as per the MySQL JDBC driver documentation be another colon between the scheme and the host.

You can paste the .jar file of the driver in the Java setup instead of adding it to each project that you create. Paste it in C:Program FilesJavajre7libext or wherever you have installed java.

After this you will find that the .jar driver is enlisted in the library folder of your created project(JRE system library) in the IDE. No need to add it repetitively.

if you are getting this exception again and again then download my-sql connector and paste in tomcat/WEB-INF/lib folder..note that some times WEB-INF folder does not contains lib folder, at that time manually create lib folder and paste mysql connector in that folder.definitely this will work.if still you got problem then check that your jdk must match your system. i.e if your system is 64 bit then jdk must be 64 bit

If the JAR file for the JDBC driver appears in the 'Referenced Libraries' branch of the project, like this:

then you don't need an import statement for it. Just use DriverManager.getConnection() and Java should be able to find the JDBC driver itself.

Dark Mode Eclipse Java

Dark Mode Eclipse Java

Dark Mode Eclipse Java Tutorial

Package Description

Bathroom behind toilet storage. However, now it provides more than just a Dark theme. It contains multiple adjustable themes to make your Eclipse IDE not only prettier but also better and easier to work with. The custom icons and color schemes in the Dark mode makes the IDE, in my opinion, visually easier to read. Now you have the ability to adapt the Eclipse visuals to your. Granted, you can forgo buying Eclipse 12 — the latest version of Eclipse — and take advantage of Smart Invert to mimic a dark mode on your iPhone instead, but the feature can invert colors that shouldn't be for a less-than-desirable look. Or you can wait for a system-wide dark mode to officially arrive when the next major iOS iteration. Step 1: Go to Window - Preferences in Eclipse Luna. Step 2: Go to General - Appearance and click on Appearance. We will find the UI as given below. Step 3: To change theme, click on theme select box, and choose Dark then click on OK. The eclipse theme will be changed. I was able to do so with the following steps: Window General Appearance Theme: Dark. File Import General Preferences Browse: theme-25999.epf Finish. When you have done that go to. Window - Preferences - General - Appearance. And change the theme from GTK (or what ever it is currently) to Dark Juno (or Dark). That will change the UI to a nice dark theme but to get the complete look and feel you can get the Eclipse Color Theme plugin from eclipsecolorthemes.org.

Want to give it a try? Get the Darkest Dark theme from the Eclipse Marketplace for free.

In a moment, we'll cover a bit of how we built this slick plugin, but first, we need to ask you for a bit of help so we can ensure that every Eclipse plugin looks amazing.

Here's the problem, there are just a lot of plugins out there and we all use different sets! So, once you install Darkest Dark, if you see something that is really funky looking, please take a moment to add an entry in our Theme Problems forum. We're targeting first the more popular plugins and places where things are just flat broken.These are things like really bad icons, or poor color choices which we can normally address very quickly if the path to reproduction is simple. Darkest Dark uses our evergreen update technology so as soon as we fix a couple of items you'll automatically get all the updates pushed into your installations so you're never out of date. Thanks in advance -- we really appreciate it!

So, how did we make this?

It was actually very hard, because it isn't really a theme. It just plays one in your Eclipse installation. Creating the Darkest Dark theme required not only using E4 styling but also creative usage of OSGi to intercept low-level calls. Our code intercepts the original icon load for something like the toolbar and returns an on-the-fly generated replacement icon. This gives the benefit of avoiding loading the original icon as well as ensuring full HiDPI support. Of course, it also provides the flexibility to tweak the colors of icons without rebuilding any images.

Where things get even hairier this how developers across the plugin community have used different patterns in building their slick UIs. For instance, there are visual designers that let people drag items together which use a combination of default colors from the theme and hardcoded colors like a bright yellow. Or other plugins where developers were using custom colors in the background of the table which contrasted on dark. In these examples, we have to intercept color load and have to return back an alternate color.

Whats up next?

Dark Mode Eclipse Java

To help us in making the replacement icons, we put together a cool Icon Editor which lets you see all of the icons that have been loaded in the Eclipse IDE including frequency of use, and create a replacement for the image. Even cooler is that when you save the updated icon, it is live-replaced into your running Eclipse IDE for many controls. I believe right now we are just missing a couple places like replacing loaded images in Image Registry caches. You can even click control-shift with your mouse over an item to find the source image. With this technology, we'll be allowing you and the community to suggest replacement icons for plugins we've missed and we'll do a light weight moderation before releasing them back to the community!

We hope you enjoy using the darkest dark theme and that you'll forgive if there are still a couple rough edges as this multi-engineer multi-month project has been a tough one. It was certainly a much larger undertaking than what we anticipated when we first started, but that turned into a benefit because if we'd known the true level of effort our management team might not have approved it!

We want to thank a few projects in particular for helping make this possible. First and foremost is Equinox and OSGi for providing the foundation that makes these creative engineering solutions possible in the first place. The Eclipse Color Theme plugin is included as part of the Darkest Dark theme to provide configurable editor colors. Work by the Eclipse platform team in Oxygen is brought forward to help clean up a couple rough areas like Button and Table header coloring on Windows. Finally, Code Affine did some nice work with flat scrollbars that provided a base to rid the UI of those nasty Windows scrollbars.

In closing I just want to point out that the Darkest Dark theme isn't just free to use, we've also made it free to redistribute. So if you have any products you've built on theEclipse platform, you may freely include Darkest Dark to deliver a rich modern dark UX to your users.

SkillPractical Spring DIY projects

Spring Boot is an open-source Java-based framework. Spring Boot is a utility for setting up an application quickly by automating the configuration procedures and speed up the process of building and deploying Spring Boot applications. It is easy to create production-ready applications using Spring Boot through embedded server(tomcat).

The solution to this is Spring Boot. Spring Boot is built on the top of the spring and contains all the features of spring. And is becoming a favorite of developers these days because it’s a rapid production-ready environment that enables the developers to directly focus on the logic instead of struggling with the configuration and set up. Spring Boot is a microservice-based framework and making a production-ready application in it takes very little time.

Prerequisites

Maven or Gradle (For this project maven is used) -  https://www.oracle.com

Java (Recommended 1.8 version or greater version) – https://maven.apache.org

IDE (It can be anything like sts, eclipse, IntelliJ, etc. but this project explained with eclipse as IDE).

Basic understanding of HTTP methods i.e. GET, POST, PUT, DELETE, etc.

Basic understanding of Spring MVC.

Advantages of Spring Boot

Container     fewer Deployments: In Spring Boot instead of deploying     application in containers (like tomcat, JBoss, etc.) it had embedded     tomcat, as a result.     a) Pre-setup of container & configuration for each environment like     development, production, etc. is not required. When the application is     ready for deployment we only need to find an environment that is capable     of running the correct version of java that our application runs.     b) For application to work we need to provide some deployment descriptive so the container understands how to deploy & serve up our application which is done in XML. but in Spring Boot no longer needed     deployment descriptive & web.xml file as Spring Boot     contains an embedded container.

Avoids writing lots of boilerplate code, Annotations. 

We can create profiles for different environments like development, production, etc.

Removed need to specify a version for dependencies in pom.xml file     & bother about versions compatibility for different libraries &     frameworks in an application.

The projects that we covered in the SkillPractical Spring are:

1. SpringBoot Getting Started  2. Create your SpringBoot App with Servlet/JSP/JDBC 3. Creating Your First RESTful Web Service with Java/SpringBoot  4. Developing Microservices with Spring Boot & Spring Cloud - Part 1  5. Developing Microservices with Spring Boot & Spring Cloud - Part 2 and etc..   

For more details on Spring DIY Projects please visit our website.

SkillPractical has Spring learning path that helps the user to learn the Java from scratch. If user have any questions on Java Spring while attempting tests, he can post a question in SkillPractical community. They will get an answer from our expert consultants.

Users can easily load hibernate documents in Hibernate using these two (2) methods. 46. What is Hibernate tuning? Optimization of the Hibernate applications performance is called Hibernate tuning. By performing SQL optimization, session management, and data caching, hibernate tuning happens. 47. What is derived properties? The unmapped properties which gets calculated at runtime via expression evaluation is called derived properties. The derived expression is received from a formula with the corresponding element. 48. What is Dialect? A single file or a group of code files that irregularly explains the procedure of connecting database to a Java class. In hibernate, a dialect plays a major role of recognizing the information that takes place with the fundamental database. 49. Describe Connection Pool? The connection pool in hibernate is a group of Database connection objects which are created for handling corresponding communication with the database. 50. Which annotation is used to specify the database table? The annotation @Table helps in specifying the database table which is allied to the entity. 51. What’s General Hibernate Flow Using Rdbms? General hibernate flow involving RDBMS is as follows: Load configuration file and create object of configuration class. Using configuration object, create sessionFactory object. From sessionFactory, get one session. Create HQL query. Execute HQL query and get the results. Results will be in the form of a list. 52. How Can We Map The Classes As Immutable? If we don’t want an application to update or delete objects of a class in hibernate, we can make the class as immutable by setting mutable=false 53.
