why we use doGet() and doPost() in the place of public void service(ServletRequest req,servletResponse resp).

we can also use service(ServletRequest req,servletResponse resp).

Why would you want to? It's much easier to use the provided methods.

The service() method is defined in GenericServlet, which was intended to be able to support different protocols. In practice you're always going to be using HTTP. The service() method is implemented in HttpServlet in a way that makes life simpler - it does all the mapping of HTTP requests for you, so all you need to do is implement the ones you want to use.

Although most people make POST and GET do the same thing, that's a really bad practice. POST and GET should be used for very different things according to the way HTTP was designed.
