Is it possible to force garbage collection in Java, even if it is tricky to do? I know about System.gc(); and Runtime.gc(); but they only suggest to do GC. How can I force GC?

推荐答案

您最好的选择是调用 System.gc（） 这仅仅是垃圾收集器的一个提示，您希望它执行收集。没有办法 force 和立即收集，因为垃圾收集器是非确定性的。

Your best option is to call System.gc() which simply is a hint to the garbage collector that you want it to do a collection. There is no way to force and immediate collection though as the garbage collector is non-deterministic.
