我正在用 Java 制作迷宫游戏。我做了一个迷宫板，一个起点和一个终点。当我到达终点时，它退出并显示获胜信息。但我不能添加时间限制。假设玩家必须在 30 秒内到达终点，否则他输掉比赛。请帮我。这是我到目前为止所做的代码......

迷宫.java

package Maze;

import javax.swing.JFrame;

public class Maze {
  public static void main(String args[])
  {
      new Maze();

  }
  public Maze()
  {
      JFrame f= new JFrame();
      f.setTitle("Maze Game");
      f.add(new Board());
      f.setSize(460,480);
      f.setLocationRelativeTo(f);
      f.setVisible(true);
      f.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
  }
}

你可以做一个工作，添加一个计时器类，它将在 x 秒执行并继续计算变量中的总秒数，当超过限制时你可以停止你的程序。
