Question

我已经有了开始按钮的代码 - 已经引用了JLabel。但是我在编写暂停/恢复和停止时遇到了麻烦。我还搜索了“计划”功能，但我不知道如何实现它。请帮忙。

    public class Timer implements Runnable {

        JLabel miliseconds;
        JLabel seconds;
        JLabel minute;

        public Timer(JLabel miliseconds, JLabel seconds, JLabel minute){
            this.miliseconds = miliseconds;
            this.seconds = seconds;
            this.minute = minute;
        }
        @Override
        public void run() {
            for (int i = 0; i < 60; i++){ 
                this.minute.setText(Integer.toString(i));
                for (int j = 0; j < 60; j++) {
                      this.seconds.setText(Integer.toString(j));
                    for (int k = 0; k < 60; k++) {

使您的线程变量成为类变量。然后在你的startActioPerformed中调用th.start（）。在pauseActionPerformed中调用th.wait（）; 并在您的resumeActionPerform中调用th.resume（）;

如何在Java中暂停/恢复和停止我的计时器？
