Java introduction

Java is a programming language supporting web technology in order to develop web applications.

Also it's a third generation high level programming language.

Java consists of 3 types:

1) SE (standard edition)

2) EE (entreprise edition)

3) ME (micro edition)

Java technologies:

1) front-end

--History of Java--

Java language was developped by SUN Micro Systems and creator is James Gosling.

The main idea behind Java Language is Common Remote Control (CRC). This project started in 1990 and named as Green Project.In 1992 this project completed, the 

device named as STAR7 and the new software given name as OAK.

Because of some issues , OAK was removed and the new software name was Java which was introduced in 1995 as JDK 1.0

In the next lesson we will learn about Java IDE's DrJava,Netbeans or Eclipse which are used to code in Java. Other IDE's can be used as well according to business needs of companies.

Then we will cover basic concepts in Java Programming such as OOP (Object Oriented Programming), applets and Swing (Developping Graphical User Interfaces in Java).
