Java Servlets are server-side Java programs that handle client requests and generate dynamic web content. They run on a web server, extending its capabilities by processing incoming requests, managing sessions, and generating responses, typically in HTML. Servlets use the Java Servlet API and are a key component of Java EE for building scalable, robust web applications. They provide a powerful, efficient way to build interactive web pages and can interact with databases, perform business logic, and integrate with other web technologies.
