java - 禁用 JAVA 上的按钮，但保留唯一的按钮

Question

根据我之前的问题: Remove a Button with same text when clicked

我需要唯一出现多个的按钮在单击时消失问题是当点击“独特”的(见图)时，它们也会消失。我的代码:

private String namesArr[] = {"Yakir","Yarden","Igor","Maoz","Moshe","Israel","Tal","Haim","Nati","Mor","Daniel","Idan"};
private Button buttonArr[] = new Button[namesArr.length];
private Font font;

public StudentsGUI(String caption) {
    super(caption);
    addWindowListener(new WindowAdapter(){
            public void windowClosing(WindowEvent e){
                    dispose();
                        System.exit(0);
                        }
                    }); 
    this.setLayout(new GridLayout(3,3));
    font = new Font("Ariel",Font.BOLD,35);

    for(int i=0;i<namesArr.length;i++) {
        buttonArr[i] = new Button(" "+namesArr[(int)(Math.random()*namesArr.length)]);
        buttonArr[i].setFont(font);
        buttonArr[i].addActionListener(this);
        this.add(buttonArr[i]);
    }
    setLocation(800,500);
    setVisible(true);
    pack();
}

public void actionPerformed(ActionEvent e) {
    if (e.getSource() instanceof Button) {
        String btnText = ((Button)e.getSource()).getLabel();
        for(int i=0; i<buttonArr.length; i++) {
            if (buttonArr[i].getLabel().equals(btnText)) {
                this.remove(buttonArr[i]);
                pack();
            }
        }
    }
}

一张图帮助你理解:

因此，如果单击“Idan”，女巫是一个独特的名称，则不会发生任何事情，因为它只有一个实例，但如果单击“Maoz”，所有带有“Maoz”标题的按钮都会消失(这已经发生了)

按照@Freddy的答案使用集合应该会更好。然而，如果你坚持使用数组，像下面这样的东西应该可以做到(虽然还没有测试过)

public void actionPerformed(ActionEvent e) {
        if (e.getSource() instanceof Button) {
            String btnText = ((Button)e.getSource()).getLabel();
            int counter = 0;
            for(int i=0; i<buttonArr.length; i++) {
                if (buttonArr[i].getLabel().equals(btnText)) counter++;
                if (count > 1) {
                   for(int j=0; j<buttonArr.length; j++) {
                      if (buttonArr[j].getLabel().equals(btnText))
                         this.remove(buttonArr[j]);
                   }
                }
            }
            pack();
        }
}
