How To Execute Shell Commands and Print Results in Java

There are many ways to execute shell commands and print results in java I guess, the famous and the most used way is Runtime.getRuntime().exec you can find a good explanation for that from here. Coming to the point i am using the same way but little different! I use BufferedReader,InputStreamReader for simplicity and I can't make it much advanced. On the main event I have created a String where you put your command with the second event it executes the command and prints the result before I start I would like to give some credits to luismcosta.

Here is the full program as I said before there's String called command where you put your shell command in. I have already added a command to ping this blog.

import java.io.BufferedReader;
import java.io.IOException;
import java.io.InputStreamReader;
//http://www.ultimateprogrammingtutorials.info
class sss {
 public static void main(String[] args) {
  final String command = "ping www.ultimateprogrammingtutorials.info";
  try {
   execute(command);
  } catch (Exception error) {
   error.printStackTrace();
  }
 }
 private static void execute(String command)
   throws IOException {
  String printline;
  java.lang.Process p = Runtime.getRuntime().exec(command);
  BufferedReader input = new BufferedReader(new InputStreamReader(p.getInputStream()));
  while ((printline = input.readLine()) != null) {
   System.out.println(printline);
  }
  input.close();
 }
}

Here's the result I got :
