計數岩石，紙張，剪刀贏得

Question

我卡住了一下如何創建一個地方將顯示多少次你贏得鬆動或繪製。像：

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

意味着，如果一個新聞紙，我贏了答案加1勝量...等等...

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

Answer 1

添加全局變量：

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

更換JWoL.setText(" You Lose |");與recordLoss();並進行功能：

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

和其他的相同。

以上可能並不完全符合您的要求，或者在您的程序的其餘部分輸出感性數據，但希望能給您足夠的指導。

但我的像，而風扇：（enum可能是比較正確的，但我覺得這是凌亂的Java）

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}; 
    ... 

更換JWoL.setText(" You Lose |");與record(LOSS);和相同的其他人，並且只有1個功能：

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