java - 计算石头、剪刀、布的获胜次数

Question

我有点困惑如何创建一个字段，其中将显示您获胜或平局的次数。喜欢:

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

意思是，如果我和新闻报纸赢得了答案，则获胜次数加 1...依此类推...

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

Answer 1

添加全局变量:

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

将 JWoL.setText("You Lose |"); 替换为 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。

上面的内容可能并不完全是您想要的，或者在程序的其余部分的上下文中输出有意义的数据，但希望能为您提供足够的指导。

但我更喜欢这样的东西:(enum可能更正确，但我觉得它在Java中很困惑)

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};
  ...

将 JWoL.setText("You Lose |"); 替换为 record(LOSS); ，其他相同，只有 1 个功能:

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