Introduction of java

Introduction

          Earlier programming languages were structured. With the popularity of c++ , there has been a new programming paradigm introduced it is object oriented programming. It involves building a program or a system from objects. In the word of Grady Brooch OOP is “ OOP is a method of programming in which programs are organized as cooperative collection of objects, each of which represents an instance of some class , and whose classes are all members of a hierarchy of classes united via inheritance relationship.”

          Java is one such object oriented programming language. Java is a programming language which is platform independent and very secure for use on internet.

 History

Java was conceived by James Gosling, Patrick Naughton, Chris Warth, Ed Frank, and Mike Sheridan at Sun Microsystems, Inc. in 1991.  The team is known as Green project team.

Java did not design for the internet. The objective behind the development of java is to create a common development environment for consumer electronic devices which was easily portable from one device to another.

The java development begum by using c++ as their model but The trouble with C and C++ (and most other languages) is that they are designed to be compiled for a specific target. Although it is possible to compile a C++ program for just about any type of CPU, to do so requires a full C++ compiler targeted for that CPU. The problem is that compilers are expensive and time-consuming to create. An easier—and more cost-efficient—solution was needed. In an attempt to find such a solution, Gosling and others began work on a portable, platform-independent language that could be used to produce code that would run on a variety of CPUs under differing environments. This effort ultimately led to the creation of Java. Originally it called “Oak”.

In 1993 the www appeared on the Internet and transformed the text based internet into a graphical – rich environment .The Green  Project team came up with the idea of developing web page called web applet using new language that could run on all types of computer s connected to Internet. The team developed a web browser called “Hot Java”.

In 1995 the Oak renamed as Java . Java was the name chosen because it sounded the coolest. The first beta release of Java was made available for download in November 1995. Sun made a developer's kit and the source code for its product freely available to anyone who wanted it-and by that time, thousands of people and companies did.
