Java web frameworks available for building web applications. These frameworks offer various features and tools to simplify web development and promote good coding practices. Below are some well-known Java web frameworks:

1. Spring Framework: Spring is one of the most widely used Java frameworks for web development. It provides a comprehensive ecosystem that includes Spring Boot (simplified configuration for building production-ready applications), Spring MVC (Model-View-Controller framework for web applications), Spring Data (for working with databases), and more.

2. JavaServer Faces (JSF): JSF is a component-based framework for building user interfaces for web applications. It simplifies the development process by providing reusable UI components, event handling, and support for different client-side technologies.

3. Apache Struts: Apache Struts is another popular framework that follows the MVC pattern. It is known for its strong community support and has been widely used in the past for building web applications.

4. Play Framework: Play is a lightweight and high-performance framework that emphasizes simplicity and developer productivity. It supports both Java and Scala and follows a reactive approach, making it suitable for modern web applications.

5. Vaadin: Vaadin is a framework that allows you to build web applications entirely in Java. It uses a component-based architecture and abstracts away much of the front-end complexity, enabling developers to focus on server-side logic.

6. Spark Java: Spark is a micro-framework that offers a simple and expressive syntax for building web applications. It is designed to be lightweight and straightforward to use, making it an excellent choice for small projects or RESTful APIs.

7. Dropwizard: Dropwizard is a framework that combines various libraries and tools to develop RESTful web services and web applications. It promotes the use of sensible defaults and aims for easy setup and configuration.

8. Micronaut: Micronaut is a modern framework designed for building microservices and serverless applications. It offers fast startup times, minimal memory footprint, and compile-time dependency injection.
