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

最好的选择是调用 System.gc() 这只是对垃圾收集器的提示，您希望它进行收集.尽管垃圾收集器是不确定的，但没有办法强制立即收集.

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.
