帮忙查找JAVA游戏程序错误

Question

程序随机产生20—50根火柴，由人与计算机轮流拿，每次拿的数量不超过3根，拿到最后一根为胜。（使用图形界面）

Answer 2

你这程序能跑起来吗？N多处错误阿...
首先：button大小设置不对，文字显示不全
其次：页面刷新不对，有时候控件显示不出来
还有：public void actionPerformed(ActionEvent e) {
        if (e.getSource() instanceof JButton) {
            int sumMatch = (int) (Math.random() * (50 - 20)) + 20;
            tfPcshow.setText("计算机随机取了" + sumMatch + "根火柴");
        }
    }
sumMatch应该用成员变量吧？不能用局部变量阿，否则，按哪个JRadioButton都会走到出错处理里，因为成员变量sumMatch的值一直为0

Answer 4

我上面那个优化了不少地方程序本身只有两处严重错误
1、Container contrainer = getContentPane();后面加一行contrainer.setLayout(null);
2、int sumMatch =(int)(Math.random()*(50-20))+20;一行把前面的int 删除修改了以上两处可以保证程序正常运行，不过你写的东东太缺乏优化了

Answer 5

 public void actionPerformed(ActionEvent e){ 
    if(e.getSource() instanceof JButton){ 
int sumMatch =(int)(Math.random()*(50-20))+20; 
tfPcshow.setText("计算机随机取了"+sumMatch+"根火柴"); 
  } 
} 把int去掉 public int Computer(){ 
    if((sumMatch <=3)&&(sumMatch>0)){ 
JOptionPane.showMessageDialog(null, "你输了!", "TEST",JOptionPane.INFORMATION_MESSAGE); 
return sumMatch;} 
else if(sumMatch!=0){ 
      int a =(int)(Math.random()*(3-1))+1; 
          sumMatch-=a; 
          return sumMatch; 
    } 
    return 0;      
    }  
改为return a;
