Java specification (naming, code reuse)
Java extends implements

Defining Interfaces (Inerface)
java override (overriding) is a polymorphic representation of subclasses and parent classes
Java Implements Method

But implements can implement multiple interfaces, separated by commas (multiple inheritance)

Class A extends B implements c,d,e {    A a1 = new B (),//a is an instance of a parent class object, and therefore cannot access a new member or method    A a2 = new C () of a subclass definition;} Class B extends aa{    //b is an instance of a subclass object that can access not only its own properties and methods, but also the properties and methods of the parent class.    b b = new B ();}
