操作后Java Swing重启计时器

我需要我的计时器重新启动或至少在执行一行代码后添加另一个延迟。

private static class ButtonHandler implements ActionListener { public void actionPerformed (ActionEvent e) { final JButton button = (JButton)e.getSource(); Timer timer = new Timer(1000, new ActionListener() { public void actionPerformed(ActionEvent e) { String tc = random(); them.setText("They chose: " + tc + "!"); if (button == rock) { whoWins("rock", tc); } else if (button == paper) { whoWins("paper", tc); } else if (button == scissors) { whoWins("scissors", tc); } yourWins.setText("Your wins: " + yw); theirWins.setText("Their wins: " + tw); } }); timer.setRepeats(false); timer.start(); } } 

我想立即实现计时器的第二次延迟

 them.setText("they chose: " + tc + "!"); 

但我不知道该怎么做，我应该重新启动计时器，如果是这样，我会在哪里编写那行代码？ 提前致谢。

我打算将此发布到您之前的问题中 ，但似乎您已经取得了一些进展，做得很好。

好的，这个例子给你三个按钮可供选择。 当您单击一个时，它会记录您选择的内容，禁用按钮并启动等待1秒的Timer 。

然后Timer的ActionListener检查您选择的内容并更新输出，然后启动另一个等待1秒的Timer ，然后重新启用按钮……
