Object Oriented Programming In Java Pdf

OBJECT ORIENTED PROGRAMMING WITH JAVA

Object Oriented Programming is a paradigm that provides many concepts such as inheritance, data binding, polymorphism etc. Simula is considered as the first object-oriented programming language. The programming paradigm where everything is represented as an object is known as truly object-oriented programming language.

Object oriented programming has taken a completely different direction and will place an emphasis on object s and information. With object oriented programming, a problem will be broken down into a number of units .these are called objects .The foundation of oop is the fact that it will place an emphasis on objects and classes. There are

Object-Oriented Programming Basics With Java In his keynote address to the 11th World Computer Congress in 1989, renowned computer scientist Donald Knuth said that one of the most important lessons he had learned from his years of experience is that software is hard to write!

for practical purposes these concepts are explored and demonstrated using the Java programming language. While the Java programming language is used to highlight and demonstrate the application of fundamental object oriented principles and modelling techniques this book is not an introduction to Java programming.

Object-oriented programming with Java Dr. Constantinos Constantinides Department of Computer Science and Software Engineering Concordia University 2 Classes and objects A class is a template from which objects may be created. - Can have any number of instances objects. An object contains state data and behavior methods.

Every object has a class -A class defines methods and fields -Methods and fields collectively known as members Class defines both type and implementation -Type what the object is and where it can be used -Implementation how the object does things Loosely speaking, the methods of a class are its Application Programming

Philosophy of OOP Object Oriented Programming is based on the idea of instantiating objects that are of a certain class A class describes a set of objects that have the same behavior For example, all objects of the Scanner class all behave the same way In the following code Scanner scan new ScannerSystem.in The scan object is an instantiation of the Scanner class
