The main ideas behind Java's Object-Oriented Programming, OOP concepts include abstraction, encapsulation, inheritance and polymorphism. Basically, Java OOP concepts let us create working methods and variables, then re-use all or part of them without compromising security.

Concepts of Object Oriented programming: Object oriented paradigm-differences between
Object Oriented Programming and Procedure oriented programming, Basic concepts of Object
Oriented Programming,Encapsulation, Inheritance and Polymorphism. Benefits of OOP .Structure
of a C++ program, namespace, Data types, C++ tokens, identifiers, variables, constants, operators,

Overview of C language:
1.C language is known as structure oriented language or procedure oriented language
2.Employs top-down programming approach where a problem is viewed as a sequence of tasks to
be performed.
3.All program code of c can be executed in C++ but converse many not be possible
4. Function overloading and operator overloading are not possible.
5. Local variables can be declared only at the beginning of the block.
6. Program controls are through jumps and calls to subroutines.
7.Polymorphism, encapsulation and inheritance are not possible.
For solving the problems, the problem is divided into a number of modules. Each module is a subprogram.
8. Data abstraction property is not supported by procedure oriented language.
9. Data in procedure oriented language is open and can be accessed by any function.
Overview of C++ language:
1. C++ can be considered as an incremental version of c language which consists all programming
language constructs with newly added features of object oriented programming.
2.c++ is structure(procedure) oriented and object oriented programming language.
3.The file extension of C++ program is “.CPP”
4. Function overloading and operator overloading are possible.
5. Variables can be declared in inline i.e when required
6. In c++ more emphasis is give on data rather than procedures
7.Polymorphism, encapsulation and inheritance are possible.
8. Data abstraction property is supported by c++.
9. Data access is limited. It can be accessed by providing various visibility modes both for data
and member functions. there by providing data security by data hiding
10.Dymanic binding is supported by C++
11..It supports all features of c language
12.It can be called as an incremental version of c language
Difference Between Procedure Oriented Programming (POP) & Object Oriented Programming (OOP)
1 program is divided into small parts program is divided into parts called objects.
called functions.
Importance is not given to data but to Importance is given to the data rather than
2 functions as well as sequence of procedures or functions because it works
actions to be done. as a real world.
3 follows Top Down approach. OOP follows Bottom Up approach.
4 OOP has access specifiers named
It does not have any access specifier.
Public, Private, Protected, etc.
5 Data can move freely from objects can move and communicate with
function to function in the system. each other through member functions.
