Java class and Objects

Procedural programming and object oriented programming structure given below.

4. Make sub class override method of super class .

Object will be created from that class type.

Instance variables are things an object knows about itself . Instance variables represent state of an object. They have unique values for each object’s type.

Methods are called as Things an object can do.

The blueprint for an object is referred to as a class. A class specifies how to create an object of that type.

A object is like one entry in your address book. Objects have own identify ,state and behavior. We want to create two class for creating object. One class is used for type of object you want to use and other class is used for test your new class.
