PREFACE Java Programming is an introduction to computer science and applications with programming intended for readers with little or no experience. In this second edition, we added managing Input/ Output operations on files along with the first edition. We start with the most basic concepts and are careful to define all terms when they are first used. The book presents each new idea in a logical progression. Larger topics, like recursion and objectoriented programming, are divided into smaller examples and introduced over the course of several chapters. This book is intentionally concise. It is not meant to be a comprehensive presentation of Java, but rather, an initial exposure to programming constructs and techniques.

ACKNOWLEDGEMENT Many persons have contributed to make this book a reality. We would especially like to express our appreciation to Dr.K.Arul, Principal, Sri Vidya Mandir Arts & Science College, Katteri, Uthangarai for his unstinted support and encouragement. We would also like to thank Thiru.R.P.Rajee, Secretary, Sri Vidya Mandir Arts & Science College, Katteri, Uthangarai for his continuous guidance. Finally, we wish to express our sincere thanks to all our family members for their moral support.

CHAPTER - I FUNDAMENTALS OF OBJECT ORIENTED PROGRAMMING 1.1 Introduction of Java Basic Concepts of OOPs  Object  Classes  Data abstraction3  Encapsulation  Inheritance  Polymorphism  Dynamic binding  Message passing Objects Objects are the basic runtime entity in an object oriented system. Syntax: Classname objectname = new objectname(); Example: Student s1 = new Student(); Classes A class is a collection of objects in similar type. Class can contain a data members and methods. Syntax Class classname { Data members;

Java Programming

Methods; } Example: Class Student { ——————— ——————— } Data Abstraction It refers to the act representing essential features without including the background details or explanation. Encapsulation The wrapping up of data members and methods into a single unit class is known as Encapsulation.

Inheritance The mechanism of deriving a new class from old class is known as Inheritance. Old class is also known as Super class or Base class. New class is also known as Sub class or Derived class. It supports the concept of hierarchical classification. Eg:

1.3

Polymorphism Poly means many. Morph means Forms. It takes more than one forms.

There are 2 types. They are,  Run time Polymorphism  Compile time Polymorphism Dynamic Binding Binding refers to the linking of a procedure call to the code executed in response to the call. It is also known as Late Binding. Message Passing An object oriented program consists of a set of object that communication with each other.

It involves the following basic steps 1. Creating classes that define objects and their behavior

1.4

2. Creating object from class definition 3. Establishing communication among objects. 1.2 Benefits of OOPs The principal advantages are: 1. Through inheritance, we can eliminate redundant code extend the use of existing classes. 2. We can build programs from the standard working modules that communicate with one another that lead to saving of development time and higher productivity. 3. The principle of data hiding helps the programmer to build secure program. 4. It is possible to have multiple instances of an object to co-exist without any interference. 5. It is possible to map object in the problem domain to those in the program. 6. It is easy to partition the work in a project based on objects. 7. The data-centered design approach enables us to capture more detail of a model can implemental form. 8. Object-oriented system can be easily upgraded from small to large system. 9. Message passing techniques for communication between objects makes to interface descriptions with external systems much simpler. 10. Software complexity can be easily managed. 1.3 Application of OOPs  Real time system  Simulation and modeling  Object oriented database  AI and Expert system  CIM/CAM/CAD system  Neural Networks and parallel programming
