Java Swing 运行后重启定时器

Question

我需要我的计时器重新启动，或者至少在执行某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();     
    }
} 

我想在之后立即实现计时器的第二次延迟

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

但我不确定如何执行此操作，我应该重新启动计时器吗？如果是，我将在哪里编写那行代码？提前致谢。

我本来打算把这个发到你的previous question，但看来你已经取得了一些进展，干得好。

好的，因此，此示例为您提供了三个按钮供您选择。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。

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