java - 添加时间我不知道如何添加

Question

这是我的迷宫代码，我想在我的游戏中添加一个计时器，如果他在 60 秒内没有完成迷宫，它将显示游戏结束并且游戏将停止

主类 包 javamazegame;

import javax.swing.*;


public class JavaMazegame { 

    public JavaMazegame(){
      JFrame f = new JFrame();
      f.setTitle("MazeGame Version 1.0");
      f.setSize(464,485);
      f.add(new Board());
      f.setLocationRelativeTo(null);
      f.setVisible(true);
      f.setResizable(false);
      f.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);



    }

    public static void main(String[] args) {
        new JavaMazegame();
    }

}
