ThankX a million dear nuno ....
Ur help n post certainly helped me a great deal and made my concepts even clearer ...!!!
thankyou so very much once again.
i came across another solution at this forum that works really KEWL ...!
the solution that i came across is ......
import java.lang.*;
import java.io.*;
public class runWinProg {
public static void main(String[] args) {
Runtime rt = Runtime.getRuntime();
//String[] callAndArgs = { "Notepad.exe","D:\\TEMP\\Test.txt" };
String[] callAndArgs = { "calc.exe"};//,"D:\\TEMP\\Test.txt" };
          try {
          Process child = rt.exec(callAndArgs);
          child.waitFor();
          System.out.println("Process exit code is: " + child.exitValue());
          catch(IOException e) {
          System.err.println(
          "IOException starting process!");
          catch(InterruptedException e) {
          System.err.println(
          "Interrupted waiting for process!");
} //end of main method
} //end of class
