    Hi friend,

    OOPs comprises the below some concepts:

    *.Instance :
    We are able to define the an instance of the object or of the class. The class object which is created while the execution of the program is referred as "Instance".

    *. Object :
    Object is nothing but the entity of the class . see the example, A "Dog" is a class which describes all behaviors which they have. The "Pug" object is of type "Dog".

    Hi,

    The object oriented programming comprises following concepts:


    1. Inheritance:
    Using this concept the re-usability of the code can be achieved in the object oriented programming

    2. Objects:It is class entity.

    3. Data Abstraction and Encapsulation: It includes data hiding.

    4. Polymorphism

    5. Message passing

    6. Classes: It is the heart of the object oriented programming.

    Hi,

    *.We can declare any number of the class object for a single class. Methods in the object oriented programming are communicate with each other by passing message through class object.

    *. "Bottom up approach" is followed in the object oriented programming. We are not able to externally access the data of the class without any proper variable scope.

    I hope this may help you.
