Explain the architecture and components of Java servlets and their role in web application development.

Java servlets are server-side components that provide a dynamic, platform-independent approach to web application development. They are an essential part of the Java Enterprise Edition (Java EE) platform and play a crucial role in handling client requests and generating dynamic responses. Let's explore the architecture and components of Java servlets in detail: 1. Servlet Architecture: The architecture of Java servlets follows the Model-View-Controller (MVC) pattern, where servlets act as the controller component. The servlet container, typically provided by a Java EE application server, manages the lifecycle and execution of servlets. When a client sends a request to a web application, the servlet container receives the request and delegates it to the appropriate servlet for processing. The servlet then generates a response, which is sent back to the client. 2. Servlet Interface: The core component of a servlet is the Servlet interface, defined by the Java Servlet API. This interface defines methods that servlets must implement to handle client requests and generate responses. The primary methods include: * `init()`: This method is called by the servlet container to initialize the servlet before it starts handling requests. It is typically used for one-time setup tasks. * `service()`: Th....
