在代碼中添加和刪除JButtons

因此，我對Java相對陌生，嘗試使用JButtons爲棋盤和棋子創建棋盤遊戲。不過，我似乎無法通過ActionListener刪除JButton。任何意見，將不勝感激。在代碼中添加和刪除JButtons

public static void main(String[] args) { 
    checkersBeBitchin begin = new checkersBeBitchin(); 

} 

public checkersBeBitchin(){ 
    box.setLayout(new BorderLayout()); 
    makeBoard(); 
    setVisible(true); 
    setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE); 
    setLocationRelativeTo(null); 
    setSize(600,600); 
    setTitle("Checkers");

    JPanel board = new JPanel();

squares.remove？它應該閱讀squares.remove（x）？我們可以看到正方形的定義嗎？它是一個數組嗎？您必須從板上移除按鈕而不是方塊，例如board.remove(x)

對不起，它是squares.remove（x）;我只是亂搞，忘了把它恢復正常，儘管這仍然不起作用。這是我如何初始化正方形：JButton [] [] squares = new JButton [8] [8]; – 2013-03-13 14:54:49

也board.remove期望一個int，但x是一個對象。 – 2013-03-13 15:13:34

board是一個JPanel，並且應該提供一個remove（object）方法！順便說一句：也許你想用jlabel替換按鈕，而不是真正刪除它？ – 2013-03-13 15:15:06
