Java Servlet API is a standard set of interfaces and classes that provide a way to develop web applications in Java. It is a part of Java Enterprise Edition (Java EE) platform and is used to create servlets, which are Java classes that dynamically generate web content. Servlets are server-side components that run on web servers and process HTTP requests from clients.
The Java Servlet API provides the following:
1. Servlet interface and related interfaces: These interfaces define the methods that a servlet must implement.
2. HttpServletResponse and HttpServletRequest classes: These classes provide methods to handle HTTP requests and responses.
3. ServletConfig and ServletContext classes: These classes provide configuration information and access to server resources.
4. Session tracking and management: The API provides methods to manage user sessions and track user activity.
5. Filters and Listeners: These components allow developers to intercept requests and responses and perform additional processing.
Overall, the Java Servlet API provides a powerful and flexible framework for developing web applications in Java.
