Introduction

Course Objective Objective of this course is to make students familiar with the

concepts of Object Oriented Programming

Software Developers are discovering that using a object

oriented design and implementation approach can make

software development much more productive than was possible

with earlier popular techniques like “Structured Programming”.

These concepts will be reinforced by their implementation in

Java

Object Orientation

What is Object Orientation? “Object" refers to a particular instance of a class.

whereas the object can be a combination of variables, functions, and data

structures.

Object-oriented programming (OOP) is a programming

language model organized around objects rather than "actions"

and data rather than “logic”. Object-oriented or object-orientation is a software engineering concept, in

which concepts are represented as "objects“

It is a technique in which we visualize our programming problems in the form

of objects and their interactions as happened in real life

OO Model consists of several interacting objects.

7

Object Orientation

Object Orientation ExamplesConsider the objects around us in our daily life. These objects interacts with each other to perform different operations.

Object Oriented Model

What is a Model? A model is abstraction of something.

Purpose is to understand the product before using it.

Example are Highway Map , Architectural Design and

Mechanical models.

What is OO Model in Programming? In the context of programming, Models are used to understand

problem before start developing it.

Object Oriented Models can be developed by showing

interaction among objects to understand a system

implementation.

Object Orientation

Object Orientation - Advantages An Object Oriented Model Maps directly to reality as seen in the

previous examples.

An Object Oriented Model for a problem can be developed

easily

An Object Oriented Model is easily understandable.

An Object Oriented Model objects are reusable.

Implementation

Can be implemented easily by using any Object Oriented

Programming Language Like, Java in our case 14

Object Orientation

What is an Object? An Object is

Something tangible (Ali, School, House, Car)

Something conceptual (that can be apprehended

intellectually for example time date and so on..)

OOP uses objects as its Fundamental Building Blocks

Objects are the basic run time entities in an object oriented

system

Every object is associated with data and functions which

defines meaningful operations on that object

Object is a real world existing entity 15

Object Orientation

What is an Object? An Object has

State (Attributes)

Well-defined behaviour (Operations)

Unique Identity

16

Object Orientation

What is an Object? An Object is an entity that has state, behaviour and identity.

There are many object around us. For Example, a computer mouse is an object. It is considered as

an object with state and behavior

Object Oriented Programming

What is Object Oriented Programming? Object Oriented Programming (OOP) is an engineering approach

for building software systems based on the concepts of classes and objects that are used for modeling real world entities

Object Oriented programming is an approach that provides a way of modularizing programs by creating partitioned memory area of both data and functions that can be used as template for creating copies of such modules on demand

Object Oriented programming is a programming methodology that associates data structure with a set of operators which act upon it. 20

Object Oriented Programming

What is Object Oriented Programming? Object-oriented programming is a programming methodology

characterized by the following concepts:

1.Abstraction.

2.Encapsulation

3.Information hiding

4.Polymorphism

5.Inheritance
