我在编程方面很新，我一直在尝试在Java上创建一个简单的二十一点游戏，但是我对分数计数有问题。
有时它会识别实际的卡值并正常工作，其他则只是定义了整个游戏的随机值和混乱。我已经使用1到52的数字将卡随机定义为"数组"，因此将它们设置为" Jlabel"作为游戏流动。分数计数设置为"开关"，该"开关"定义了每张卡的值。
这是我的代码，请帮助我：

我没有附近的编译器，但是这是我通过阅读您的代码看到的错误。
您在哪里声明：card = new Int [53];它正在创建一个从0-52的数组，实际上是53个值，因此假设您有53张卡。适当的声明将是：card = new int [52];因为那样，它是从0-51的数组制成52个值的数组。
