System.exit(0);
}//end try
catch (IOException e)
System.out.println("exception Happened" );
e.printStackTrace();
System.exit(-1);

It works fine if you replaceProcess p = Runtime.getRuntime().exec("c:\\dir");withProcess p = Runtime.getRuntime().exec("cmd /c dir");And don't forget to define your s variable.
