（draw_amount您的代码将无法编译，因为您使用了do{}while循环，该循环具有一般形式：
do {
statement(s)
} while (expression);
并且，您没有在其中三个中添加表达式部分（从代码开始）。
你写没有表达式的语句
我不知道您的代码，但足以添加：
}while(true);
}
}while(true);
}
}while(true);
}
}
编辑它
但是，您应该认真考虑将代码划分为多个类和方法，因为这很难读取和维护（您可能知道）.你必须描述你的程序到底是如何无法产生预期结果的。很难将你的问题从所有这些代码中分离出来，特别是如果你不说明它是什么。你能描述一下你到目前为止尝试了什么，你期望发生什么，以及它到目前为止做了什么吗？我运行它时的问题是：语法错误，插入“while”（表达式）；“若要完成DoStatement语法错误，请插入“}”若要完成MethodBody我尝试运行程序，但以下错误总是显示语法错误，请插入“while（表达式）；”若要完成DoStatement语法错误，请插入“}”完成MethodBody。我正在尝试做一个atm机程序。伙计们。嗯，你需要注意你的问题的标题，无论如何，等我读了你的代码再回答
