Java
Java represents a number of computer software products and
specifications from Sun Microsystems that provide a system for
developing application software and deploying it in a cross-platform
environment.
Java is a network-aware language superficially resembling C
and C++, but much
smaller and more compact and cleanly designed. It's an unlimited-extent
language with garbage collection like Lisp, but with static type
checking.
The Java plaform consists of several programs including:
- Java Virtual Machine (JVM), a set of computer software
programs and
data structures which use a virtual machine model for the execution of
other computer programs and scripts
- Java Compiler
- Java
Runtime Environment, executes .class or .jar files, emulating the JVM
instruction set by interpreting it, or using a just-in-time compiler
(JIT)
- Class libraries provide:
- a well-known set of functions to perform common tasks
- an abstract interface to tasks that would normally depend
heavily on the hardware and operating system
- APIs
The
vast majority of Java's source code has been released under the GPL.
However, there remains a few parts which are only distributed
as
precompiled binaries, without source code.

Features include:
- Software written in the Java language run on any supported
hardware/operating-system platform. In other words, a program can be
written once, compiled once, and run on multiple operating systems
- Java
syntax borrows heavily from C and C++ but it eliminates certain
low-level constructs such as pointers and has a very simple memory
model where every object is allocated on the heap and all variables of
object types are references
