Introduction for Java
Java is Object oriented language because it supports all oops concepts. We cover the topics that the Introduction for Java and History of Java and its basics.
It is a high level programming language and it is not understandable by machine in introduction for java. Java was firstly developed by Sun Microsystems which was initiated by “James Gosling” and java was released in 1995 as core component of the ‘Sun Microsystems’ Java platform (Java 1.0 [J2SE]) and later it is implemented and undertaken by Oracle. And now we are using or latest version of java is Java 8.0 [J2SE]. There are 2 more versions java 9(older version) and java 10(latest version).
There are three latest J2 versions of java they are:
1. J2SE: It is a Java Standard edition. The latest version of Java Standard edition is Java SE 8.It can work on various types of platforms.
2. J2EE: J2EE means Java Enterprise Edition. It is used for enterprise applications. Java EE are increasing day by day.
3. J2ME: J2ME means Java Mobile Edition. It is used for the implementation mobile applications.
Java can run anywhere it is a slogan given by Sun Microsystems “Write once, run anywhere”, or sometimes it maybe “write once, run everywhere”. It was a catchphrase said by Sun Microsystems because they want say benefits of Java programming language.
History and Introduction for Java
Java was first initiated by James Gosling. James Gosling originated Java project in June 1991 for use of his many set-top box designs and programs. The Java language, firstly called as ‘Oak’ after an oak tree that stood outside Gosling’s office, also went by the name ‘Green’ and ended up later being renamed as Java, from a list of random words.
Sun Microsystems released first version of Java in 1995 the version is Java 1.0. Java aasured Write Once, Run Anywhere (WORA), it providing no cost and it runs on popular or various types of platforms.
Sun Microsystems announced Java for free and open source software for everyone under the terms of the GNU General Public License (GPL) in 13th November 2006.
On 8th May 2007, Sun Microsystems finished the process and making of all Java’s core code for free and open-source, seperately from a small segment of code to which Sun did not hold the copyright.
James Gosling is known as the “Father of Java“. At present James Gosling is working as chief technology officer at Sun Microsystems. But now java is under taken by Oracle. Java was the first programming language that was designed with internet in mind and which is used to highly distributed applications. Java is First initiates by James Gosling later it is worked by some others.
