推荐答案

您不需要（也不应该尝试使用）析构函数 - 或者在Java中调用它们：终结器 。

You do not need (nor should you try to use) destructors - or what they are called in Java: "Finalizers".

VM规范允许VM实现永远不会调用它们。因此，它们对资源发布等不可靠。一般来说，在对象被垃圾回收之前，VM可以调用任何对象的 finalize（）方法中的代码，但由于这不是强制性的，所以应该避免使用它。

The VM specification does allow for VM implementations to never call them. So they are not reliable for resource releases and the like. Generally speaking the code in the finalize() method of any object can be called by the VM before the object is garbage collected, but as this is not mandatory, you should avoid it.
