我无法让我的游戏正确翻转瓷砖。我被困在这无数个小时，似乎无法解决这个问题。我已经检查了其他Reversi代码示例，但遗憾的是仍然没有骰子。我注意到，每当我点击gui中的一个被占用的BoardPiece时，程序都没有意识到它被占用了。鼓励任何批评/帮助！提前致谢。

答案 0 :(得分：0)
你有不同的变量同名。
class BoardSquare extends JLabel {
private Index index;
private Color c = Color.white;
private Border b = BorderFactory.createLineBorder(Color.BLACK, 2);
BoardSquare(Index index, final Color c) {
addMouseListener(new MouseAdapter() {
public void mouseClicked(MouseEvent e) {
if (e.getButton() == 1) {
if (c == Color.white) {
你的意思是c？ final Color c或private Color c？我认为您意味着 private Color c，但您使用的是final Color c。
我建议：
class BoardSquare extends JLabel {
private Index index;
private Color myColor = Color.white;
private Border b = BorderFactory.createLineBorder(Color.BLACK, 2);
BoardSquare(Index index, final Color initialColor) {
addMouseListener(new MouseAdapter() {
public void mouseClicked(MouseEvent e) {
if (e.getButton() == 1) {
if (myColor.equals(Color.white)) {
（未经测试）
更好的是将mouseListener添加到更高层。 （您在构造函数中泄漏this，即bad）
for (int column = 0; column < 8; column++) {
index = new Index(row, column);
BoardSquares[row][column] = new BoardSquare(index, Color.white);
BoardSquares[row][column].addMouseListener( .. );
