In a servlet, the **doGet** method is a part of the HTTP servlet's life cycle and is designed to handle HTTP GET requests. The **doGet** method is automatically called by the servlet container when a client sends an HTTP GET request to the servlet. It's one of the key methods for processing client requests in a servlet. Let's break down its purpose and usage:

## Method Signature:

- The **doGet** method is defined in the **HttpServlet** class and is overridden in your servlet class.

## Handling GET Parameters:

- Use the **HttpServletRequest** object to access parameters sent in the URL or as part of the query string in a GET request.

## Processing the Request:

- Perform any necessary processing based on the information in the request. This could include retrieving data from a database, generating dynamic content, or any other business logic.

## Automatic Invocation:

- The **doGet** method is automatically invoked by the servlet container when a client makes an HTTP GET request to the servlet's URL.

## Configuring URL Mapping:

- In the **web.xml** file or using annotations, you need to configure the servlet to handle specific URL patterns. This tells the servlet container when to call the **doGet** method.

In summary, the **doGet** method in a servlet is responsible for handling HTTP GET requests. It processes incoming requests, accesses parameters, performs necessary business logic, and sends an appropriate response back to the client. The servlet container automatically calls this method when a client sends an HTTP GET request to the servlet's specified URL pattern.
