MVC Interview Questions and Answers For 2 Years Experience

1. What do you meant MVC? MVC is a framework pattern that splits an application’s implementation logic into three component roles: models, views, and controllers.

Model: The business entity on which the overall application operates. Many applications use a persistent storage mechanism (such as a database) to store data. MVC does not specifically mention the data access layer because it is understood to be encapsulated by the Model.

View: The user interface that renders the Model into a form of interaction.

Controller: Handles a request from a View and updates the Model that results in a change of the Model’s state.

To implement MVC in .NET we need mainly three classes (View, Controller and the Model).

2. What is meant by ASP.Net MVC The ASP.Net MVC is the framework provided by Microsoft to achieve separation of concerns that leads to easy maintainability of the application. Model is supposed to handle data related activity View deals with user interface related work Controller is meant for managing the application flow by communicating between Model and View.

3. What are the new features of MVC2? ASP.NET MVC 2 was released in March 2010. Its main features are:

Introduction of UI helpers with automatic scaffolding with customizable templates.

Attribute-based model validation on both client and server.

Strongly typed HTML helpers.

Improved Visual Studio tooling

There were also lots of API enhancements and “pro” features, based on feedback from developers building a variety of applications on ASP.NET MVC 1, such as:

Support for partitioning large applications into

Asynchronous controllers support.

Support for rendering subsections of a page/site using Html.RenderAction.

Lots of new helper functions, utilities, and API enhancements

Hibernate Interview Questions and Answers For Experienced

Q1. What is the difference between sorted and ordered collection in hibernate? Sorted Collection: The sorted collection is a collection that is sorted using the Java collections framework. The sorting is done in the memory of JVM that is running hibernate, soon after reading the data from the database using Java Comparator The less the collection the more the efficient of sorting Ordered Collection: The order collections will also sorts a collection by using the order by clause for the results fetched.The more the collection, the more efficient of sorting.

Q2. Describe your favorite aspect of the Hibernate framework. There are a lot to choose from, but I’d say my favorite thing is that Hibernate is that it’s an object-oriented query language. There are a lot of potential answers to this question. The interviewer just wants to see where your values lie.

Q3. Explain the main difference between Entity Beans and Hibernate Entity beans are to be implemented by containers, classes, descriptors. Hibernate is just a tool that quickly persist the object tree to a class hierarchy in a database and without using a single SQL statement. The inheritance and polymorphism is quite simply implemented in hibernate which is out of the box of EJB and a big drawback.

Q4. What is your least favorite aspect of the Hibernate framework? It does a lot of things right, but I often find myself having to write boilerplate code while using Hibernate. The verbosity of the language makes my job more difficult. Once again, the interviewer wants to see where your values lie.

Q5. Explain the difference between Hibernate and Spring. Hibernate is an ORM tool for data persistency. Spring is a framework for enterprise applications. Spring supports hibernate and provides the different classes which are templates that contains the common code.

Spring MVC Interview Questions and Answers For Experienced

Q1. What is “Spring Framework” ? With the two core concepts of Aspect-Oriented and Dependency Injection, Spring is one of the most popular and widely used Java EE frameworks. Through dependency injection it can provide tight coupling between various components. The cross-cutting tasks such as authentication and logging can be provided through Spring framework and the aspect-oriented programming can be implemented through this as well. Spring framework is a featured framework which can provide several modules and lots of features for the specific tasks such as Spring JDBC and Spring MVC. Working with Spring is quite easy and a fun activity due to the presence of a number of online communities and resources.

Q2. Why Spring Framework is needed? Spring framework is needed because it is –

Very Light Weight Container

Framework

IOC

AOP

Q3. What are the advantages of Spring Framework? Spring framework offers a number of advantages which includes the following:

The direct dependency among several components can be reduced through Spring IoC containers. They are responsible to create the beans, which are injected between the components and to reduce the dependency.

As the business logic does not have any direct dependency on the implementation class of actual resource so it becomes quite easier to write the Unit test cases. The test configurations can be easily written and the configurations can be injected easily for testing purposes.

The amount of boilerplate code is also reduced e,g. to open or close the resource or to initialize an JdbcTemplate class can also remove the boilerplate code required in JDBC programming.

Spring framework can help us in keeping the application lightweight say e.g if Spring transaction management feature is not required, then the user needs not to add that dependency to the project.

Spring framework can support a number of Java EE framework features even more than Spring is always top of the technologies like to write better naïve android application user can use Spring project for Android. So it can be a complete package and user need not have any separate package for the work.
