Java Framework

Here are some popular Java frameworks:

1. Spring Framework: Spring is one of the most widely used Java frameworks, primarily focused on building enterprise-level applications. It offers features like dependency injection, aspect-oriented programming, and various modules for building web applications (Spring MVC), data access (Spring Data), and more. Spring Boot simplifies the setup of Spring applications.

2. Hibernate: Hibernate is an object-relational mapping (ORM) framework that simplifies database interaction in Java applications. It allows developers to work with Java objects and databases without writing SQL queries explicitly.

3. JavaServer Faces (JSF): JSF is a Java web application framework that simplifies the creation of user interfaces for web applications. It provides a component-based architecture and facilitates the development of rich, interactive web applications.

4. Apache Struts: Struts is a framework for building web applications following the Model-View-Controller (MVC) architectural pattern. It helps structure the application’s code and separates concerns.

5. Play Framework: Play is a reactive web application framework that focuses on developer productivity and scalability. It is well-suited for building modern web applications, including RESTful APIs.

6. Vaadin: Vaadin is a framework for building web applications with Java on the server-side. It allows developers to create rich, single-page applications (SPAs) using Java as the primary language.

7. Apache Wicket: Wicket is a component-based web application framework that emphasizes reusable components and a Java-centric development approach.

8. Apache Camel: Camel is an integration framework that simplifies the integration of various systems, services, and protocols using a wide range of predefined components.

9. JUnit: JUnit is a popular framework for writing and running unit tests in Java applications. It is widely used for test-driven development (TDD) and test automation.

10. JavaFX: JavaFX is a framework for building rich client applications, including desktop and mobile applications with modern user interfaces.

11. Vert.x: Vert.x is a reactive, event-driven framework for building scalable and resilient applications, including web applications and microservices.
