System.runFinalization()建议不被使用，会造成不稳定

i think your question is about the difference between garbage collection and finalization.
Simply speaking, garbage collection is just to RECLAIM the MEMORY occupied by unused object, and it is only about the memory. However finialization is to clean up an object. It means that if there is some activity that must be performed before you no longer need an object, you must perform that activity yourself (quite possibly in your finalize method). ( While it is not same as the destructor in C++). Finalize is not used much.Top

第一个不是手动调用垃圾回收器吗
第二个不太清楚 好相是调用在垃圾回收之前必须调用的那个东东吧
我觉的最好自己都别手工调用Top
