我有点不知道如何创建一个文件，其中将显示你赢得松散或平局的次数。喜欢：

| Wins:  | 234 |
| Looses:| 234 |
| Draws: | 434 |

意思是，如果我和一篇新闻报纸赢得了答案，则获胜次数加 1……等等……

| Wins:  | 235 |
| Looses:| 234 |
| Draws: | 434 |

添加全局变量：

public class gui extends JFrame implements ActionListener
{
  int wins = 0, losses = 0, draws = 0;
  ...

替换JWoL.setText(" You Lose |");为recordLoss();并创建一个函数：

private void recordLoss()
{
  JWoL.setText(" You Lose |");
  losses++;
  JNumLose.setText(""+losses);
}

其他人也一样。

以上可能不是您想要的或在程序其余部分的上下文中输出敏感数据，但希望能给您足够的指导。

但我更喜欢这样的东西：（可能enum更正确，但我觉得它在 Java 中很乱）

public class gui extends JFrame implements ActionListener
{
  static final int WINS = 0, LOSSES = 1, DRAWS = 2;
  int[] counts = new int[3];
  String[] strings = {" You Win |", " You Lose |", " Tie |"};
  // this MUST be set up in the constructor, not here!
  JLabel[] labels = {JNumWin, JNumLose, JNumTie};
  ...

替换JWoL.setText(" You Lose |");为record(LOSS);和其他的相同，并且只有1个功能：

private void record(int type)
{
  JWoL.setText(strings[type]);
  counts[type]++;
  labels[type].setText(""+counts[type]);
}
