Java Code to Ping an IP Address

Here is a sample Java code for pinging an ip address:

 import java.io.*;  
 import java.util.*;  
 public class JavaPingExampleProgram  
 {  
  public static void main(String args[])   
  throws IOException  
  {  
   // create the ping command as a list of strings  
   JavaPingExampleProgram ping = new JavaPingExampleProgram();  
   List<String> commands = new ArrayList<String>();  
   commands.add("ping");  
   commands.add("-c");  
   commands.add("5");  
   commands.add("www.google.com");  
   ping.doCommand(commands);  
  }  
  public void doCommand(List<String> command)   
  throws IOException  
  {  
   String s = null;  
   ProcessBuilder pb = new ProcessBuilder(command);  
   Process process = pb.start();  
   BufferedReader stdInput = new BufferedReader(new InputStreamReader(process.getInputStream()));  
   BufferedReader stdError = new BufferedReader(new InputStreamReader(process.getErrorStream()));  
   // read the output from the command  
   System.out.println("Here is the standard output of the command:\n");  
   while ((s = stdInput.readLine()) != null)  
   {  
    System.out.println(s);  
   }  
   // read any errors from the attempted command  
   System.out.println("Here is the standard error of the command (if any):\n");  
   while ((s = stdError.readLine()) != null)  
   {  
    System.out.println(s);  
   }  
  }  
 }
