Question

I want to know that in servlets why we use doGet and doPost methods together in the same program. What is the use of it??

What does the following code means?
Why to call the doGet method from doPost? I am not at all clear about this code.

public class Info extends HttpServlet
{

public void doGet(HttpServletRequest request, HttpServletResponse response)
throws IOException, ServletException
 {

 }


public void doPost(HttpServletRequest request, HttpServletResponse response)
throws IOException, ServletException
{
    doGet(request, response);
}
}

Thanks

Simply, it is to make the servlet generalized so that even if we change the request method in future, it is not required to edit the servlet, which will reduce the efforts to modify the application in future.
