推荐答案

if条件后面的代码块需要运行多次以增加n的值(您也可以使用'n ++ ；而不是'n = n +1;').是这样吗?您的代码段没有显示该内容.

The code block behind your if condition needs to run for multiple times to increment the value of n (you could also use 'n++;' instead of 'n = n + 1;').  Is that the case? Your snippet doesn't show that.

而且，您的变量n一定不能成为单独的线程(例如，在方法中声明的变量)的一部分，该线程在if条件再次得到评估(并且n得到递增)之前已经完成，否则可能会被垃圾回收.你在哪里申报 变量n?

And, your variable n must not be part of a separate thread (e.g. a variable declared in a method) that gets finished before the if condition gets once more evaluated (and n gets incremented), otherwise it might get garbishcollected. Where do you declare the variable n?
