Java represents a number of computer software products and specifications from Oracle Corporation (previously developed by 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.
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.
- 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.
