Java is a programming language originally developed by James Gosling at Sun Microsystems
(which has since merged into Oracle Corporation) and released in 1995 as a core component of Sun Microsystems' Java platform.
The language derives much of its syntax from C and C++ but has a simpler object model and fewer low-level facilities than either C or C++. Java applications are typically compiled to bytecode (class file) that can run on any Java Virtual Machine (JVM) regardless of computer architecture. Java is a general-purpose, concurrent, class-based, object-oriented language that is specifically designed to have as few implementation dependencies as possible. It is intended to let application developers "write once, run anywhere" (WORA), meaning that code that runs on one platform does not need to be recompiled to run on another.
Java is as of 2012 one of the most popular programming languages in use, particularly for client-server web applications, with a reported 10 million users.
There are lots of applications and websites that won't work unless you have Java installed, and more are created every day. Java is fast,
secure, and reliable. From laptops to datacenters, game consoles to scientific supercomputers, cell phones to the Internet, Java is everywhere!
There were five primary goals in the creation of the Java language :-
- It should be "simple, object-oriented and familiar"
- It should be "robust and secure"
- It should be "architecture-neutral and portable"
- It should execute with "high performance"
- It should be "interpreted, threaded, and dynamic"
