这不是一个可以调试的问题。对于内存限制，您使用的内存太多。没有一行代码可能导致此问题

相反，您需要使用探查器来确定内存的使用位置。我建议您尝试将最大内存增加到略低于主内存的一半，并附加一个探查器VisualVM总比什么都没有好，并查看对象是否保留在哪里

如果您使用商业探查器，这将运行得更好，并且更清楚问题所在。我使用你的工具包，你可以免费获得评估许可证

我错过了开关箱n++内的增量运算符。所以循环永远不会结束

我会养成像这样使用for循环的习惯

这不是一个可以调试的问题。对于内存限制，您使用的内存太多。没有一行代码可能导致此问题

相反，您需要使用探查器来确定内存的使用位置。我建议您尝试将最大内存增加到略低于主内存的一半，并附加一个探查器VisualVM总比什么都没有好，并查看对象是否保留在哪里

如果您使用商业探查器，这将运行得更好，并且更清楚问题所在。我使用你的工具包，你可以免费获得评估许可证

我错过了开关箱n++内的增量运算符。所以循环永远不会结束

我会养成像这样使用for循环的习惯

for(int i = 0; i <= 19; i++)
当堆中使用的内存高于允许的内存或者对象（如列表）变得太大以至于超过JVM分配的内存时，就会发生这种情况。
这可以通过处理数组来解决，比如在不需要对象时清空它们、使用垃圾收集器刷新内存、尝试不在循环中使用数组以及简单地处理堆栈。除非绝对必要，否则简单地增加JVM允许的内存是不好的做法。

除非绝对必要，否则请增加JVM允许的内存。

由于JVM内存不足，因此出现此错误。您需要通过设置JVM参数来增加java堆大小。 我想问题可能在这里

在上面的代码中，您并没有增加n的值。所以，在ArrayOfSums类中，当u在while循环中的哪个位置增加n时？？？在开关盒内。我最后应该输入n++。Stackoverflow.com不是构建更好的Stackoverflows的指南。@PeterRader这不是堆栈溢出，而是堆溢出-@chrylis很明显，这是发布到错误的交换中的。在你的while循环中，u在哪里增加n？？？在ArrayOfSums类的开关盒中。我最后应该输入n++。Stackoverflow.com不是构建更好的Stackoverflows的指南。@PeterRader这不是堆栈溢出，而是堆溢出-@很明显，这封信当时寄错了。谢谢你的帮助。我自己也发现了。我错过了开关箱n++内的增量运算符。所以循环永远不会结束。这导致了这个错误。谢谢你的支持，谢谢你的帮助。我自己也发现了。我错过了开关箱n++内的增量运算符。所以循环永远不会结束。这导致了这个错误。谢谢你的支持，谢谢你的帮助。我自己也发现了。我错过了开关箱n++内的增量运算符。所以循环永远不会结束。这导致了这个错误。谢谢你的支持，谢谢你的帮助。我自己也发现了。我错过了开关箱n++内的增量运算符。所以循环永远不会结束。这导致了这个错误。谢谢你的支持，谢谢你的帮助。我错过了开关箱n++内的增量运算符。所以循环永远不会结束。这导致了这个错误。谢谢你的支持。@Thennarasuravandran我已经更新了我的答案。您想限制局部变量的范围。谢谢您的帮助。我错过了开关箱n++内的增量运算符。所以循环永远不会结束。这导致了这个错误。谢谢你的支持。@Thennarasuravandran我已经更新了我的答案。您想限制局部变量的范围。谢谢您的帮助。我错过了开关箱n++内的增量运算符。所以循环永远不会结束。我刚才找到了。谢谢你的帮助。我错过了开关箱n++内的增量运算符。所以循环永远不会结束。我刚才找到了。谢谢你谢谢你的帮助。谢谢你，谢谢你的帮助。非常感谢。
