What is the difference between HttpServlet and GenericServlet in Servlets?

It provides methods to handle HTTP GET, POST, PUT, DELETE, etc. requests and generate responses. In contrast, GenericServlet is a generic, protocol-independent servlet that needs to be extended to handle specific protocols.

Therefore, the focus keyword "difference between HttpServlet and GenericServlet" in servlets lies in their functionality and the specific focus on handling HTTP requests by HttpServlet compared to the protocol-independent nature of GenericServlet.
