Handling JOptionPane.CANCEL_OPTION ?

Question

hi
i'm making confirmation dialog with yes,no,cancel option
and i have a problem that when i press the cancel button the program automatically exits why?
i want to do other operation when pressing cancel,but it doesn't response to any thing?
    int option = JOptionPane.showConfirmDialog(null,"Save Chages?","Warning",JOptionPane.YES_NO_CANCEL_OPTION);
            if (option == JOptionPane.YES_OPTION) {
            Save();
        else if (option == JOptionPane.NO_OPTION) {
           System.exit(0);
       else if(option == JOptionPane.CANCEL_OPTION){
                //any thing here doesn't invoke even left empty the program exits
               frame.requestFocusInWindow();
                             }

First of all, please please please clean up the indentation problems with your posted code. This is painful and at times torture. Check out camickr's rec's in your recent thread.
Next, does the line: frame.requestFocusInWindow();get called if cancel is pressed? It should. Does your program exit after this? If so, maybe this has nothing to do with the option pane and everything to do with your code stream running out of the the river. The program just naturally ended. This is hard for us to know without seeing your code in context.
Here's my version of your code, formatted
import javax.swing.JOptionPane;
class Fubar
  public static void main(String[] args)
    int option = JOptionPane.showConfirmDialog(null, "Save Chages?", "Warning",
        JOptionPane.YES_NO_CANCEL_OPTION);
    if (option == JOptionPane.YES_OPTION)
      System.out.println("Save();");
    else if (option == JOptionPane.NO_OPTION)
      System.exit(0);
    else if (option == JOptionPane.CANCEL_OPTION)
      System.out.println("frame.requestFocusInWindow();");
