Java is a pure object-oriented
programming language created by abilities best previous object
programming language (C ++, Ada, Simula). Java was created by James Gosling, the developer of Sun Microsystems in
1991.
Java is a programming language that can run on a variety of computers including mobile phones. This language was originally created by James Gosling while still joined Sun Microsystems is now a part of Oracle and released in 1995. These languages are adopting syntactic contained in C and C ++ but with syntax simpler object model and support a lower-level routines minimal. Java based applications are generally compiled into p-code (bytecode) and can run on different Java Virtual Machine (JVM). Java is a programming language that is general / non-specific (general purpose), and is specifically designed to utilize minimal implementation dependencies as possible. Because the functionality that allows Java applications can run on several different operating system platforms, also known as java slogan, "Write once, run anywhere". Currently Java is a programming language used most popular and widely used in the development of various types of software applications or web-based applications.
Characteristics of Java, among others:
- Simple (Simple)

Java has a platform that is:
- Java Virtual Machine (Java VM)
- Java Application Programming Interface (Java API)
Various Java 2 Software Developers Kit (J2SDK), among others:
- J2SE (Java 2 Standard Edition)
- J2EE (Java 2 Enterprise Edition)
- J2ME (Java 2 Micro Edition)
The Java programming language is born of The Green Project, which runs for 18 months, from early 1991 until the summer of 1992. The project is not using a version called Oak. The project was led by Patrick Naughton, Mike Sheridan, James Gosling and Zhulfikar Grace, along with nine other programmers from Sun Microsystems. One result of this project is the Duke mascot created by Joe Palrang.
Project meeting took place in an office building Sand Hill Road in Menlo Park. Around the summer of 1992 the project was closed by generating a Java program's first Oak, which is intended as a hardware controller with touch screen technology (touch screen), such as the PDA today. The new technology is called "* 7" (Seven Star).
After the era of Star Seven completed, a subsidiary of Cable Tv interested plus some of the projects The Green Project. They focus their activities on an office space at 100 Hamilton Avenue, Palo Alto.
The new company look up: the number of employees increased in a short period of 13 to 70 people. In the span of the use of the Internet is well established as a medium that bridges work and ideas between them. In the early 1990s, the Internet is still a stub, which is used only in academic circles and the military.
They are made of (browser) Mosaic as an initial basis for making the first browser, called Java Web Runner, inspired by 1980s film, Blade Runner. In the development of the first release, the Web Runner renamed Hot Java.
In about March 1995, for the first time the Java source code version 1.0a2 opened. Their success was followed by coverage for the first time in the newspaper San Jose Mercury News on May 23, 1995.
Unfortunately there was a division among them one day at 04.00 in a hotel room Sheraton Palace. Three of the main leaders of the project, Eric Schmidt and George Paolini from Sun Microsystems along with Marc Andreessen, Netscape formed.
Name Oak, taken from an oak tree growing in front of the window workspace "Father of Java", James Gosling. Oak's name is not used to release version of Java as an other software has been registered with the trademark, the replacement name into "Java". The name is taken from the ground pure coffee directly from the seeds (black coffee) Gosling's favorite. It is said that this coffee comes from Java. So the name of the Java programming language is none other comes from the word Java (English for Java is a Java).
The initial version of Java in the year 1996 has been a release version so called Java Version 1.0. Java
version includes many standard package starting to be developed in the next version:
java.lang: Appropriation basic elements of the class.
java.io: Appropriation input and output classes, including the use of the file.
java.util: Appropriation complementary class of data structures such as class and class calendar class.
java.net: The Allocation class TCP / IP, which allows to communicate with other computers using TCP / IP network.
java.awt: The base class for applications with user interface (GUI)
java.applet: The base class application interface to be implemented on a web browser.
