How to close the program in Java completely in Swing

A Java Swing application can be closed using the following code segment to retrieve the parent of the container, check if it is a JFrame and then dispose the JFrame:

	public class btnCancelListener implements ActionListener {
		public void actionPerformed(ActionEvent ev) {
			Container bframe = btnCancel.getParent();
			bframe = bframe.getParent();
			while (! (bframe instanceof JFrame)) {
				System.out.println("Done");
				((JFrame) bframe).dispose();
			}
		}
	}
