Servlet Interface MEthods:
See What is-
1.init() 
2.service()
3.destroy()  

Main code to understand:


import java.io.IOException;
import javax.servlet.ServletException;
import javax.servlet.annotation.WebServlet;
import javax.servlet.http.HttpServlet;
import javax.servlet.http.HttpServletRequest;
import javax.servlet.http.HttpServletResponse;

/**
 * Servlet implementation class InitDestroDemo
 */
@WebServlet("/InitDestroDemo")
public class InitDestroDemo extends HttpServlet {
private static final long serialVersionUID = 1L;



public void init(){

System.out.println("It is under Init Method");
}



@Override
protected void service(HttpServletRequest arg0, HttpServletResponse arg1) throws ServletException, IOException {
       System.out.println("it is Service");
}

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

System.out.println("It is under doGet");


}

@Override
public void destroy() {
System.out.println("It is under destroy method");
}

}

1.init()

it loads when server starts

2.Service()

call each time servlet loads....
use service method in place ofdoPost and doGet that is not method specific and no fear of 405 error.


3.Destroy
