Handling HTTP GET requests involves overriding the doGet method. The following example shows the use of HTTP GET method.

import java.io.*;

import javax.servlet.*;

import javax.servlet.http.*;

public class HelloWorld extends HttpServlet{

public void doGet(HttpServletRequest req, HttpServletResponse res) throws ServletException, IOException{

res.setContentType(“text/html”);

PrintWriter pw = res.getWriter();

pw.println("<html>");

pw.println("<head>");

pw.println(“<title>HW</title>”);

pw.println("</head>");

pw.println("<body>");

pw.println("<h2>Hello World!</h2>");

pw.println("</body>");

pw.println("</html>");

pw.close();

}
