java learning - members access properties and methods inherited overwritten (concept)

/ *
In the parent-child class inheritance relationships among objects create a subclass, the members of the rules of access methods:
objects created who, with a priority on who, if not then look up.

Note:
Whether a member or member variables method, if no parent is looking up, never looking down subclass.

Rewrite (Override)
concept: the inheritance among the same method name, parameter list, too.

Rewrite (Override): Like the name of the method, the parameter list [too]. Cover, overwritten.
Overload (Overload): Like the name of the method, the parameter list [different].

Covering methods of rewriting features: create a subclass object, the priority sub-class method.
