import javax.swing.AbstractAction;
import javax.swing.Action;

public class Main {

  public static void main(String[] args) {
    Action closeAction = new CloseAction();
    closeAction.putValue(Action.SHORT_DESCRIPTION, "Closes the application");
    closeAction.putValue(Action.MNEMONIC_KEY, KeyEvent.VK_C);
  }/* www  .j av a2  s.co  m*/
