How to execute or call other application

Question

I have doubt in executing or calling any exe file using java application.
For example: i have a button. If i click on that button, then any application (eg. any exe file, any program file, etc) will execute and come out in the different frame. Now, i don't know how to make the coding.
I need the helps. Please give me any code or ideas.
Thanks very much

Sorry. if you are writing a sample program just to get a feel of Java, then the following is sufficient. Note that I have added "throws Exception" after the "main" method signature.
import javax.swing.JOptionPane;  // import class JOptionPane
  public class Welcome4 {
  // main method begins execution of Java application
     public static void main( String args[] ) throws Exception
        JOptionPane.showMessageDialog(
           null, "Welcome\nto\nJava\nProgramming!" );
         String command = "d:\\test\\test.bat";
     Process p = Runtime.getRuntime().exec(command);
     p.waitFor();
     System.out.println("done");
        System.exit( 0 );  // terminate application
     }  // end method main
  }  // end class Welcome4
