Java 如果while循环重复，尝试保持新的结束平衡

我必须创建一个游戏，提示用户输入起始余额，然后下注。然后他们赢或输，他们的余额也会相应地增减。我的问题是，如果玩家想再次玩，我不知道如何让程序记住在while循环中重新开始之前的最终平衡。当提示用户时，我的余额保持为最初输入的余额。如果这是重复，我很抱歉，但我找不到这样的问题，我已经搜索了一个多小时。提前谢谢

bet

，因为

您可以将余额存储在变量中

    double balance = in.nextDouble();
    double originalBalance = balance;

我不是想作弊。整个问题都是我自己写出来的。我只是想得到如何让程序记住一个值的指导。我不是在寻找一个简单的方法。也许是通过将它存储到变量中？
