我正在使用eclipse创建一台老虎机
我试图以某种方式更新“奖金”JTextField，以便在选择随机图像时，它会添加到已经显示在JTextField中的数字，而不是它在分钟时所执行的操作。显示在特定旋转中获胜的数量。
我也在努力设置代码，以便在获得注释时，不添加任何内容。任何帮助，将不胜感激。干杯
我的代码：

答案 0 :(得分：1)
为奖金维护一个单独的变量，可能是double。计算每轮的奖金并将其添加到变量中，然后使用Double.toString或NumberFormat.getNumberInstance().format(...)之类的内容将值转换为String并将其设置为文本字段的文本
例如......
if(a==b && a==c ){
winnings += 100;
}
else if (a==b || a==c || b==c)
{
winnings += 50;
}
else if (a== 3 || b== 3 ||c== 3){
winnings += 20;
}
txtwinnings.setText(NumberFormat.getInstance().format(winnings));
