Java is a high quality (open source) object oriented programming language which
has gained immense popularity worldwide.

Java was originally developed by Sun Microsystems 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.

Java applications are typically compiled to bytecode that can run on any Java
virtual machine (JVM) regardless of computer architecture.

Java was designed to be platform independent - "write once run anywhere".
