Pause execution until the child dialog is closed

问题

I am trying to open a JDialog from JFrame. I want to pause the execution until the child dialog is being closed, but the main frame is being executed continuously without any pause. I am using the following code.

What is alternate solution?

Class NewFrame extends JFrame

 NewFrame()

  try 
    {
       NewDialog frm = new NewDialog();
       frm.show();

       JOptionPane.showMessageDialog(null,"yes");
     }
  catch(Exception ex)
   {
   ex.printStackTrace();
  }
 }
}

In the above program I want a message should be displayed when the dialog box should be closed.

Make sure that NewDialog is extend from JDialog and is set to modal (setModal(true)). You might like to take a look at How to use Dialogs
