java - 带有 JButton 的 ActionListener 问题

Question

我正在为我的第一个 Java 课程开发一个游戏。我必须用两个不同的动作监听器创建两个不同的按钮。TreasureButton 从 EmptyButton 扩展而来，每个都有不同的侦听器。

我遇到的问题是，当我尝试在空按钮侦听器中设置测试时，它会覆盖 TreasureButton 侦听器。例如，宝藏按钮文本设置为“$”。如果我将空按钮文本设置为“X”，那么所有按钮都会显示为“X”，即使它是宝藏。我还必须创建最后移动标签和文本字段。当我在空按钮侦听器下运行该方法以将最后一步作为“胸围”执行时，即使我发现宝藏，它也只会说“胸围”。我在我的 TreasureButtonListener 类中尝试了@Override，但它没有改变任何东西。对此有何指导？

import javax.swing.*;
public class EmptyButton extends JButton
{
    //has-a TreasureGame
    private TreasureGame game;
    
    //has-a TreasureGameView
    private TreasureGameView gameView;
    
    public EmptyButton(TreasureGame game, TreasureGameView gameView)
    {
        super();
        setText("X");
        this.game = game;
        this.gameView = gameView;
        
        addActionListener(new EmptyButtonListener(this, game, gameView));
    }
}
