Explaining the Lifecycle of a Servlet

In the world of Java web development, understanding the lifecycle of a Servlet is crucial. A Servlet goes through several phases during its lifecycle:

1. Initialization: During this phase, the Servlet container loads the Servlet class, creates an instance of it, and calls the init() method to initialize the Servlet.
2. Request Handling: When a client sends a request to the Servlet, the Servlet container calls the service() method, which in turn calls the doGet(), doPost(), doPut(), doDelete(), etc., depending on the type of request.
3. Response Generation: The Servlet processes the request, generates a response, and sends it back to the client.
4. Destroy: Finally, when the Servlet container decides to remove the Servlet instance, it calls the destroy() method to clean up any resources held by the Servlet.

Understanding the lifecycle of a Servlet helps developers write efficient and robust Java web applications.
