/ * 
* Member method inheritance features 
* not in the subclass this method, call the parent class 
* subclasses override this method, call the subclass 
* 

   override methods: In the child-parent class among subclasses exactly the same methods and the parent class, subclass overrides a parent class (covering), when the child class overrides the parent method, using a method that is a subclass of the subclass object calls the 
   overloaded methods: in a class, there are multiple methods of the same name, but not the same parameter (the sequence number of parameters, parameter types, parameters), return values, and irrelevant 

* overridden methods application scenario: when the parent class is not fully meet the subclasses, the parent class subclass overrides this time, 
* and can use the keyword super to call the parent class in the method, which can do so to maintain the function of the parent class, sub-class can have a unique function 
* 
* Note overridden method: 
the method can not override the parent class * private 
* permissions permission must be greater than equal to the parent class method 
* 
* Notes: @ 
* @Override: You can verify method in a subclass and parent class Like, if and The method is different from the parent class error. (@Override not without error but the method is the new method does not inherit the parent class method)
