java - 如何删除内部类ActionListener？

Question

我正在制作一个基于文本的游戏，但我遇到了一个相当大的问题。这个问题是，当我将新的 ActionListener 分配给已经分配了 ActionListener 的按钮时，它会执行这两个操作。这是我的代码:

       while(shouldLoop) {
       if(Player.loc == 1) {
       left.setText("Do nothing");
       left.addActionListener(new ActionListener() {
           @Override
           public void actionPerformed(ActionEvent e) {
           nar1.setText("You are still in a dungeon."); //Here's my first assignment
       }
       });
       right.setText("Pick the lock");
       right.addActionListener(new ActionListener() {
           @Override
           public void actionPerformed(ActionEvent e) {
               Player.loc = 2;
           }
       });
       } if(Player.loc == 2) {
               nar1.setText("You are now outside");
               nar2.setText("the door. What now?");
               forward.addActionListener(new ActionListener() {
                   @Override
                   public void actionPerformed(ActionEvent e) {
                       nar1.setText("You hear a guard.");
                       nar2.setText("What do you do now?");
                       Player.loc = 3;
       }
               });
               left.addActionListener(new ActionListener() {   //Here's another
                   @Override                                   //assignment to
                   public void actionPerformed(ActionEvent e) {//the same button
                       nar1.setText("You hear a guard.");      //so when I press
                       nar2.setText("What do you do now?");    //it here, it
                       Player.loc = 3;                         //performs the
                   }                                           //original assignment
               });
               right.addActionListener(new ActionListener() {
                   @Override
                   public void actionPerformed(ActionEvent e) {
                       nar1.setText("You hear a guard.");
                       nar2.setText("What do you do now?");
                       Player.loc = 3;
                   }
               });
               right.setText(rgt);
               forward.setText(fwd);
               back.setText(bck);
               left.setText(lft);
               forward.setVisible(true);
       } if(Player.loc == 3) {
           forward.setVisible(false);
           right.setText("Sneak around him!");
           left.setText("Fight him!");
       }

为什么不直接将 addActionListener 代码从 while 循环中提升出来呢？
