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?

Your most suitable option is to call System.gc() which is a reference to the garbage collector that you want it to do a combination. There is no way to force and direct collection though as the trash collector is non-deterministic.
