我正在开发一个面向Java面向对象编程的Mastermind游戏，除了代码的一部分外，我还有一切工作
if(uG[0].getIcon() == compGuess[0].getIcon() && uG[1].getIcon() == compGuess[1].getIcon() && uG[2].getIcon() == compGuess[2].getIcon() && uG[3].getIcon() == compGuess[3].getIcon())
{
JOptionPane.showMessageDialog(f1, "You have guessed them all coorect!", "Mastermind: Test Your Mind", JOptionPane.INFORMATION_MESSAGE);
submit.setEnabled(false);
compGuess[0].setEnabled(false);
compGuess[1].setEnabled(false);
compGuess[2].setEnabled(false);
compGuess[3].setEnabled(false);
compGuess[0].setVisible(true);
compGuess[1].setVisible(true);
compGuess[2].setVisible(true);
compGuess[3].setVisible(true);
uG[0].setEnabled(false);
uG[1].setEnabled(false);
uG[2].setEnabled(false);
uG[3].setEnabled(false);
System.exit(0);
}
我正在添加完整的代码，因为上面的代码^^显示我的问题在哪里，但你无法弄清楚为什么它不按预期的方式工作，除非你查看原始的完整代码。是的，可能需要一两分钟才能通读，但这有助于解决手头的问题。您可以将音频部分注释掉并更改图标。当它运行时，计算机猜测将不会显示，直到你猜对了，但这就是问题所在。即使你猜对了，游戏也不会在你猜到10次之后。我无法弄清楚为什么会这样。有人可以帮忙吗？

先谢谢周杰伦！
答案 0 :(得分：0)
您描述的问题是通过比较不同的引用而引起的。
compGuess数组被类似的东西初始化（分布在你的代码中，但基本上就是这样）：
// colored2[0] contains filename
final ImageIcon cell1 = new ImageIcon(colored2[0]);
compGuess[0] = new JButton();
compGuess[0].setIcon(cell1);
即。您创建JButton并为该按钮分配新创建的ImageIcon。
另一方面，uG我们有代码
uG[0] = new JButton();
uG[0].setIcon(new ImageIcon("circle-red.png")); // inside mouse listener
表示您再次创建一个按钮，并为该ImageIcon分配另一个uG[0].getIcon() == compGuess[0].getIcon()
实例。
所以比较时
enum DiskColor { RED, BLUE, GREEN, YELLOW };您实际上比较了图标实例，这些图标实例当然从不匹配，因为它们是独立创建的，因此始终是不同的对象。
要解决此问题，您可以创建一次每个不同的图标，并为所有组件共享/重用它。但我更喜欢不同的方式并将表示（图标）与底层数据模型分开，并且都存储了一个合适的（与视图无关的）数据类型（例如{{1}}），您可以轻松地进行比较，但也可以进行转换进入你的视图表示。
答案 1 :(得分：-1)
如下所示：
Thread.sleep(1000);
System.exit(0);
在显示用户正确猜到该号码的代码上。我认为问题是在后台运行了非守护程序线程，并且您没有指定您希望程序结束。
