Netbeans 中带有 Java GUI 的 Tic Tac Toe 游戏显示不正确

Question

我的目标是在两个玩家（没有 computerized/random 玩家）之间创建一个可以重新开始的 TicTacToe 游戏。我有大部分代码，但是当我运行代码而不是在文本字段中说“X's turn”或“O's turn”时，它直接进入 'X wins ' 或 'O wins' 甚至'wins'。我将如何修复此错误？

Answer 1

问题可能出在你的 if 语句上。
因为如果单击按钮，您将更改按钮文本。
尝试

if(button1.getText().equals("X")&&button2getText().equals("X")&&button3.getText().equals("X")){
text.setText(button1.getText() + " wins!");
}
