Java 操纵变量？

此程序将值添加到名为money的变量中，该变量最初设置为0，具体取决于生成的数字（素数、复合数、平方数或其他）

我知道如果我有两个相同的数字，那么它总是产生0。 我几乎可以肯定11的倍数，复合数和素数总是产生正确的值

例如，当我得到52（复合）、73（素数）、13（素数）、56（复合）、64（平方）和23（素数）的随机数时，我得到的返回值是708，但答案应该是716

52+100+100+56=308*2=616+100=716

正方形的循环一定有问题，有人能看到任何可能不会产生正确结果的东西吗？谢谢大家!

我不知道你到底想要什么，但你就不能这样做：

money *= 2;

还是这个

money += money;

而不是这个

money += DoubledMoney;

顺便说一句：与其执行100倍的ifs，不如在if中添加更多条件，如下所示：

if(HouseNumber1 == i || HouseNumber2 == i || HouseNumberX == i){
 // do the work
}

您可以缩短一堆代码，以减少在许多地方重复出现错误的机会。我还换了钱*=2；这应该是你想要的。希望我在这漫长的过程中没有把你的东西搞砸。P.S.还没有在IDE中测试过这一点

如果你只是想要双倍的钱，为什么你不能简单地做

钱*=2if（HouseNumber1==i）{..}

中添加

DoubleMoney

？在你需要双倍资金的地方也一样。我不知道，我现在就试试。非常感谢。我会让你知道它是否有效。只要有一个正方形，它就不能正确计算。我知道这是双倍的数字，但有些事情是错误的。是的，我明白你关于国际单项体育联合会的观点，我一开始确实这样做了，但没有意识到我可以轻易地再做一次。hagubear提到了你上面提到的钱*=2，我确实改变了它，如果你运行这个程序，我有时得不到我想要的答案，我想我必须检查每一行，以确保我知道它在做什么，而不仅仅是我认为它在做什么。这将是一个非常乏味的过程。谢谢你！那太令人印象深刻了，谢谢你。我现在就测试它。你能修复这行代码吗？Set lump=新的HashSet（）；它找不到Set或HashSet的符号。是否需要将文件保存为特定名称？
