yes

You hav asked "have u used "post" method"

import java.io.IOException; import java.io.PrintWriter;

import javax.servlet.ServletException; import javax.servlet.http.HttpServletRequest; import javax.servlet.http.HttpServletResponse;

public class PatternExample extends javax.servlet.http.HttpServlet implements javax.servlet.Servlet { /** * */ private static final long serialVersionUID = 1L;

protected void doPost(HttpServletRequest request, HttpServletResponse response) throws ServletException, IOException 
{        
    response.setContentType("text/html");        
    PrintWriter out=response.getWriter();

    String number1=request.getParameter("num1");
    String number2=request.getParameter("num2");

    int n1=Integer.parseInt(number1);
    int n2=Integer.parseInt(number2);

    for(int i=n1;i<=n2;i++)
        {   
        for(int j=n1;j<i+1;j++)
        {   
                out.print(j);   
        }   
        out.println("<br>");   
        }       
    }
}

this is the servlet and;

<form method="post" action="/PatternExample">

Enter start: <input type="text" name="num1"><br>

Enter end  : <input type="text" name="num2"><br>

<input type="submit" value="Submit" onclick="PatternExample.java">



</form>

this is jsp file and i think both contain POST method so i guess it contains post method~!!!!!

Make changes in PatternExample.java:

import java.io.*;
import java.sql.*;
import javax.servlet.*;
import javax.servlet.http.*;

public class PatternExample extends javax.servlet.http.HttpServlet implements javax.servlet.Servlet { 

public void doPost(HttpServletRequest request, HttpServletResponse response) throws ServletException, IOException {
        response.setContentType("text/html");
        PrintWriter out=response.getWriter();

String number1=request.getParameter("num1");
String number2=request.getParameter("num2");
int n1=Integer.parseInt(number1);
int n2=Integer.parseInt(number2);
for(int i=n1;i<=n2;i++){
   for(int j=n1;j<i+1;j++){
   out.print(j);
   }
   out.println("<br>");
    }
        }
        public void doGet(HttpServletRequest request, HttpServletResponse response)throws ServletException, IOException {
        this.doPost(request, response);
}
}

Compile your servlet. Then restart the server and then run the pattern.jsp.
