Ping and Ipconfig by pop-up window in Java Netbeans

Good day everyone, I write to see how I can do an Ipconfig and a ping in java netbeans by popup window in which I ask the user the ip you want to ping, I currently have it to appear by console but I can not pass it to appear by window emergent. The code is as follows:

package ping;

import java.io.BufferedReader;
import java.io.InputStreamReader;
import java.io.IOException;
import javax.swing.*;

import java.io.BufferedReader;
import java.io.InputStreamReader;

public class ping2 {

    public static void runSystemCommand(String command) {

        try {
            Process p = Runtime.getRuntime().exec(command);
            BufferedReader inputStream = new BufferedReader(new InputStreamReader(p.getInputStream()));

            String s = "";
            // reading output stream of the command
            while ((s = inputStream.readLine()) != null) {
                System.out.println(s);
            }

        } catch (Exception e) {
            e.printStackTrace();
        }
    }

    public static void main(String[] args) {

        String ip = "192.168.40.215";
        runSystemCommand("ping " + ip);
    }
}

I appreciate if someone can help me.
