Java permits a class to replace (or override) a method that it has inherited. A subclass can define a method with the SAME signature as a superclass method.
Overloading
Two methods have the same name but DIFFERENT signatures — the parameter types and/or the number of parameters are different.
public StringBuilder append (int a); public StringBuilder append (String s); public StringBuilder append (int a, int b);
Overriding
A method in the subclass has the SAME signature as a method in the superclass.
Calling An Overridden Method Within a subclass definition, you can call the superclass method with the “super” reference.
