Inherited constructors were already discussed: A super class's constructor is always called before a subclass's constructor, but the same is not true of finalizers. A super class's finalizer is not executed unless the subclass's finalizer explicitly calls it. Furthermore, it must be the last method called by subclass's finalizer. To invoke the super class's constructor you access it through the super variable, for example:
public class MyClass extends MySuperClass { protected void finalize() { // Clean up this class super.finalize(); } }
Thus, if MyClass's finalizer is invoked, the last thing it does is call MySuperClass's finalize method.
