Introduction to Java Programming is a textbook for software developers to familiarize them with the concept of object-oriented programming (OOP). The textbook enables the reader to understand the basic features of Java. The line-by-line explanation of the source code, a unique feature of the textbook, enables the students to gain a thorough and practical understanding of Java. The chapters in this book are structured in a pedagogical sequence, which makes this textbook very effective in learning the features and capabilities of the software.

The following are some additional features of this book: >

• Each concept discussed in the book is exemplified by an application to clarify and facilitate better understanding.
• This textbook introduces the key ideas of object-oriented programming in an innovative way.
• The concepts are illustrated through best programs, covering the basic aspects of Java.
• Additional information is provided to the users in the form of notes.
• There is an extensive use of examples, schematic representation, screen captures, tables, and programming exercises.

Introduction to Java

Learning Objectives

After completing this chapter, you will be able to:

• Understand history, evolution, and features of Java

• Understand the concept of OOPS

• Understand Java complier and interpreter

• Install Java development kit

• Write, compile, set the path, and run your first Java program

• Install NetBeans IDE

• Write, build, and run Java program in NetBeans IDE

Introduction

This chapter introduces you to Java programming language and allows you to write your first program in Java. In this chapter, you will get a brief idea about history, evolution, and features of the language. Also, you will learn how to install Java and Net Beans IDE (Integrated Development Environment) on your system and run Java programs. Moreover, you will gain knowledge about the concept of object oriented programming as well as its importance in developing Java programs.

Note

1. An Integrated Development Environment (IDE) is a software application that provides comprehensive features to computer programmers for software development. It generally consists of a source code editor, build automation tools, and a debugger.

2. The examples in this book are tested on Windows platform which is itself written in Java.

HISTORY AND EVOLUTION OF JAVA

The first version of Java was developed by James Gosling at Sun Microsystems (which has since been acquired by Oracle Corporation) in USA, in the year 1991. Initially, it was named as Oak by James Gosling, but later in 1995, it was renamed to Java. The first version of the application was developed for the use of electronic devices and circuits, and the plan got successful. Later on, it was called the Green project that led to the invention of Java.

Apart from its general purpose use, it is considered as a leading web-based technology. When it was invented, nobody knew how popular it would be. It is the first object oriented programming language that is platform independent and can run on any platform. It allows the developers to follow “Write Once, Run Anywhere” (WORA) concept. Though the base syntax of Java has been taken from C and C++, s...
