Currently, I am actively looking for projects in my company. I have attended a few interviews and they really make me realise that I have a lot of gaps in knowledge and understanding.

Since I am in the java track, I have been attending a few interviews for java projects. The only experience I have ahd is to use java ee with apache ant, so you can imagine how much knowledge I am lacking on.

Some concepts that they tested on in the interview:

- DTOs

- Rest APIs and how do you store keys in production

- Binding

- How do you use Jenkins to do CICD

- Maven concepts

I also went for an interview for data analytics and they tested me on Sql concepts:

- joins

- aggregate functions

- other functions like roll number, rank, dense rank

- he asked me the difference between having and group by??

Developing Open Source Programming Libraries

Open source libraries are essential tools that drive innovation and collaboration in the programming world. They help developers save time, encourage knowledge sharing, and improve software quality. If you've ever thought about giving back to the developer community, building your own open source library is a fantastic way to start.

What is a Programming Library?

A programming library is a collection of reusable code, functions, or classes that help developers perform common tasks without rewriting code from scratch. Examples include libraries for handling dates, making HTTP requests, or performing complex mathematical operations.

Why Build an Open Source Library?

Contribute to the community: Help other developers solve problems and build better software.

Enhance your skills: Learn software design, testing, and documentation.

Build your reputation: Demonstrate your knowledge and gain recognition in the dev community.

Get feedback: Collaborate with developers from around the world and improve your code.

Steps to Build an Open Source Library

Identify a Problem: Find a common pain point or a repetitive task that you can simplify with code.

Plan Your Library: Outline features, structure, and language-specific conventions.

Write Clean Code: Use modular, readable, and well-documented code.

Include Tests: Unit and integration tests ensure your library works as expected.

Write Documentation: Explain how to install, use, and contribute to your library.

Choose a License: Pick an open source license (like MIT, GPL, Apache) to define how others can use your code.

Publish Your Library: Share it on GitHub and package it for ecosystems like npm (JavaScript), PyPI (Python), or crates.io (Rust).

Tools You Might Use

Git & GitHub: For version control and collaboration.

CI/CD Tools: Like GitHub Actions for automating tests and deployments.

Package Managers: npm, pip, Maven, etc., depending on your language.

Documentation Tools: JSDoc, Sphinx, or MkDocs to generate professional docs.

Best Practices

Keep your code simple and focused on solving one problem well.

Write thorough documentation and usage examples.

Be responsive to issues and pull requests.

Encourage contributions and create a welcoming community.

Use semantic versioning (SemVer) for clear version management.

Example: A Simple JavaScript Utility Library

Here's a snippet of a function that could go in a utility library: // utils.js export function capitalize(str) { return str.charAt(0).toUpperCase() + str.slice(1); }

You can package this as an npm module and publish it with clear usage instructions and tests.

Conclusion

Building an open source library is a great way to level up as a programmer while making a real impact. Whether it's a simple utility or a full-featured framework, your library can help others while showcasing your skills. Start small, stay consistent, and join the world of open source contributors!

How to install Apache Maven | Software Testing

[fromdevcom]

Do you want to know what every Java developer should know? We have shortlisted some of the highly recommended concepts and components of Java language for beginners and senior programmers. These things to learn in Java may help you get the best Java developer job you deserve. Java technology has evolved and has become really huge in the last decade. There are just too many things and its almost impossible for one person to master all of them. Your knowledge about Java technology will depend completely on what you working on. In any technology say Java or some other language, it is more important and valuable to know the language fundamentals thoroughly (OOP concepts, interfaces, class, objects, threading, etc.) rather than specific frameworks or syntax. It's always easy to quickly learn new technologies when you master the fundamentals. Are you are a beginner? Looking for some help and guidance on how to get started on this language, our exclusive article on How to Learn Java and Java libraries to know is a must read for you before getting started on Java. I just updated this article in November 2016 and things are more relevant to recent Java trends. Java Interview Preparation Tips Part 0: Things You Must Know For a Java Interview Part 1: Core Java Interview Questions Part 2: JDBC Interview Questions Part 3: Collections Framework Interview Questions Part 4: Threading Interview Questions Part 5: Serialization Interview Questions Part 6: Classpath Related Questions Part 7: Java Architect Scalability Questions Java developers knowledge expectation changes based on the profile. In this post I have divided it into 3 profiles: College Graduate, Experienced Java Developer, Experienced Java Web Developer. 7 Things a College graduate must know to get a Java developer job If you are a college graduate with no job experience then as a Java developer you need to understand the following basic things. How Java Virtual Machine works? e.g. (Platform Independence, Garbage Collection, class files, etc) What are the Object-Oriented Programming Concepts Implemented in Java? Multi-threading Java Collection framework Good understanding of data types and few of "java.lang" classes like String, Math, System, etc. java.io stream concepts. Understand the concept of Swing/AWT event-based programming. Do not spend a lot of time on this but understand the best practices.  Servlets and JSP concepts.  9 Things an experienced Java Developer must know to thrive If you are an experienced professional then as a Java developer you may also need to understand the following basic things in addition to the ones listed above. Understand design patterns and its usage in Java Improvements in language from major version changes (Lambda, NIO, Generics, Annotations, Enums, ...). Coding Conventions. Build tool (Ant) or Project Management Tool (Maven). Version control System like GIT/SVN/Perforce/Clearcase. Apache Commons Libraries & few other common open source libraries. Continuous Integration Tools e.g. Jenkins and Hudson. Unit testing - e.g. JUnit and TestNG Unit testing Mocking libraries like Mockito Fundamental understanding of JSON and XML Understand Business layer frameworks - like Spring Understanding dependency injection (e.g. Spring, Google Guice, and Plain Java Dependency injection) 4 Things a Java Web Developer (JEE) Developer must know If you are an experienced professional working on Web-based development then as a JEE developer you also need to understand the following basic things in addition to the ones (7+9) listed above. Understanding of MVC Frameworks - Open source web frameworks like - Spring MVC, Struts, Vaadin, etc. Understanding of Microservice based framework like Spring Boot. Important Note: A lot of Front End UI development is now shifted to JavaScript frameworks. Therefore do not focus on Java-based frameworks that focus on the user interface (e.g. JSF or related frameworks).

Instead, learn JavaScript related frameworks like Angular.js or Backbone.js Fundamental understanding of Web Services and REST based service development. Good understanding of Web/Application server like Tomcat, Glassfish, WebLogic, WebSphere, Jetty, etc. Unix environment - A working knowledge of Unix environment can be beneficial as most of the Java servers are hosted on Unix based environment in production. Looking at the list of things it really feels difficult for a person to know each and everything in depth. As I already said it is more important and valuable to know the language fundamentals thoroughly and rest can be learned quickly when required. Can you think of something which is not part of this post? Please don't forget to share it with me in the comments section & I will try to include it in the list. Article Updates Article updated in April 2019 - Updated Introduction section, fixed minor text, and updated answers. Updated on November 2016 - Made changes as per latest technology trends and stacks.
