如何在java中創建自動關閉消息框

Question

我想創建一個消息框，它將在沒有用戶輸入的情況下自動關閉。我試着閱讀幾個Java教程。它是一個計時器類。但我找不到代碼示例。

有人可以幫我做到這一點。一個小的代碼示例將沿着這些路線的偉大

public class AutoDismiss implements Runnable, ActionListener 
{ 
    private JDialog dialog; 

    public AutoDismiss(JDialog dialog) 
    { 
     this.dialog = dialog; 
    } 

    @Override 
    public void actionPerformed(ActionEvent e) 
    { 
     dialog.dispose(); 
    }  

    // EDIT: in response to comment 
    static public void showMessageDialog(Component parent, Object message) { 
     // run all of this on the EDT 
     final JOptionPane optionPane = new JOptionPane(message); 
     String title = UIManager.getString("OptionPane.messageDialogTitle"); 
     int style = styleFromMessageType(JOptionPane.INFORMATION_MESSAGE); 
     final JDialog dialog = optionPane.createDialog(parent, title, style); 
     Timer timer = new Timer(5000, new AutoDismiss(dialog)); 
     timer.setRepeats(false); 
     timer.start(); 
     if (dialog.isDisplayable()) 
      dialog.setVisible(true); 
    } 
}
