This document provides an overview of the Java programming language, including its history, applications, versions, features, components, and platforms. Java is an object-oriented language designed to be platform independent so that code can run on any device. It has a wide variety of uses including for mobile apps, web apps, enterprise software, and more. The language was created in 1991 and released publicly in 1995 with the goals of being fast, secure, and reliable.

2. Java is a general-purpose, class-based, object-oriented
programming language designed for having lesser
implementation dependencies. It is a computing platform
for application development. Java is fast, secure, and
reliable, therefore. It is widely used for developing Java
applications in laptops, data centers, game consoles,
scientific supercomputers, cell phones, etc.

5. James Gosling initiated Java language project
in June 1991 for use in one of his many set-top
box projects. The language, initially called ‘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 released the first public implementation
as Java 1.0 in 1995. It promised Write Once,
Run Anywhere (WORA), providing no-cost run-
times on popular platforms.
HISTORY OF JAVA
On 13 November, 2006, Sun released
much of Java as free and open source
software under the terms of the GNU
General Public License (GPL).
On 8 May, 2007, Sun finished the process,
making all of Java's core code free and
open-source, aside from a small portion
of code to which Sun did not hold the
copyright.

6. Versions 1.0 and 1.1 are named as JDK (Java Development Kit).
From versions 1.2 to 1.4, the platform is named as J2SE
(Java 2 Standard Edition).
From versions 1.5, Sun introduces internal and external versions.
Internal version is continuous from previous ones (1.5 after 1.4), but
the external version has a big jump (5.0 for 1.5). This could make
confusion for someone, so keep in mind that version 1.5 and version
5.0 are just two different version names for only one thing.
From Java 6, the version name is Java SE X.
Major versions were released after every 2 years, however the Java
SE 7 took 5 years to be available after its predecessor Java SE 6, and
3 years for Java SE 8 to be available to public afterward.
Since Java SE 10, new versions will be released very six months.
