使用Swing计时器将动作暂停xxx秒的示例：
import java.awt.*;import java.awt.event.*;import javax.swing.*;@SuppressWarnings("serial")public class QuickTimerEg extends JPanel { private static final int TIMER_DELAY = 2000; private boolean buttonsWorking = true; private JButton btn1 = null; private JButton btn2 = null; private Timer swingTimer; public QuickTimerEg() { ActionListener btnListener = new ActionListener() { public void actionPerformed(ActionEvent e) { btnActionPerformed(e); } }; setLayout(new GridLayout(4, 4)); for (int i = 0; i < 4; i++) { for (int j = 0; j < 4; j++) { JButton button = new JButton(" "); button.addActionListener(btnListener); add(button); } } } private void btnActionPerformed(ActionEvent e) { if (!buttonsWorking) { return; } JButton button = (JButton)e.getSource(); button.setBackground(Color.blue); button.setEnabled(false); if (btn1 == null) { btn1 = button; } else { buttonsWorking = false; btn2 = button; swingTimer = new Timer(TIMER_DELAY, new ActionListener() { public void actionPerformed(ActionEvent e) { btn1.setBackground(null); btn2.setBackground(null); btn1.setEnabled(true); btn2.setEnabled(true); btn1 = null; btn2 = null; buttonsWorking = true; } }); swingTimer.setRepeats(false); swingTimer.start(); } } private static void createAndShowGui() { Jframe frame = new Jframe("QuickTimerEg"); frame.setDefaultCloseOperation(Jframe.EXIT_ON_CLOSE); frame.getContentPane().add(new QuickTimerEg()); frame.pack(); frame.setLocationRelativeTo(null); frame.setVisible(true); } public static void main(String[] args) { SwingUtilities.invokeLater(new Runnable() { public void run() { createAndShowGui(); } }); }}
