Java History:

James Gosling, Mike Sheridan, and Patrick Naughton are the actual developers of Java language project in June 1991. Java language was initially called Oak after an oak tree that stood outside Gosling's office; it went by the name Green later, and was later renamed Java, from Java coffee, said to be consumed in large quantities by the language's creators. Sun Microsystems released the first public implementation as Java 1.0 in 1995.

Java versions as of today:

Major release versions of Java, along with their release dates:
-> JDK 1.0 (January 21, 1996) -> JDK 1.1 (February 19, 1997) -> J2SE 1.2 (December 8, 1998) -> J2SE 1.3 (May 8, 2000) -> J2SE 1.4 (February 6, 2002) -> J2SE 5.0 (September 30, 2004) -> Java SE 6 (December 11, 2006) -> Java SE 7 (July 28, 2011) -> Java SE 8 (March 18, 2014)

The features that made java so powerful:

1.Java is platform independent. 2.Java language is easy to learn. 3.Java is Object Oriented programming language. 4.Java can be used to build heavy enterprise applications. 5.Java is open source software. 6.With java you can wirte secure and robust applications. 7.Architecture neutral.

What is Java?

Java is both a programming language and a platform.

What advantages we get with java?

Get started quickly:

Although the Java programming language is a powerful object-oriented language, it's easy to learn, especially for programmers already familiar with C or C++.

Write less code:

Comparisons of program metrics (class counts, method counts, and so on) suggest that a program written in the Java programming language can be four times smaller than the same program written in C++.

Write better code:

The Java programming language encourages good coding practices, and automatic garbage collection helps you avoid memory leaks. Its object orientation, its JavaBeansTM component architecture, and its wide-ranging, easily extendible API let you reuse existing, tested code and introduce fewer bugs.

Develop programs more quickly:

The Java programming language is simpler than C++, and as such, your development time could be up to twice as fast when writing in it. Your programs will also require fewer lines of code.

Avoid platform dependencies:

You can keep your program portable by avoiding the use of libraries written in other languages.

Write once run anywhere:

Because applications written in the Java programming language are compiled into machine-independent bytecodes, they run consistently on any Java platform.

Distribute software more easily:

With Java Web Start software, users will be able to launch your applications with a single click of the mouse. An automatic version check at startup ensures that users are always up to date with the latest version of your software. If an update is available, the Java Web Start software will automatically update their installation.
