Java is a programming language originally developed by
James Gosling at 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 (class
file) that can run on any Java Virtual Machine (JVM)
regardless of computer architecture. This programming
language is a general purpose concurrent class based object
oriented programming language, specifically designed to
have as few implementation dependencies as possible. It is
intended to let application developers "write once, run
anywhere".
When Java Code is compiled a byte code is generated which
is independent of the system. This byte code is fed to the
JVM (Java Virtual Machine) which is resided in the system.
Since every system has its own JVM, it doesn't matter where
you compile the source code. The byte code generated by the
compiler can be interpreted by any JVM of any machine.
Hence it is called Platform independent Language.
