Java
Java is an object-oriented programming language, developed in 1995 by SUN MICROSYSTEMS in order to obtain a small, easy-to-use, fast and multiplatform product.
Java compiles source of its programmes in a code called Bytecode, different from the language used the computer where it is compiled on.
In order to run a programme you have to use a tool, the Java Virtual Machine, which translates the bytecode coming from the compiler and runs it on the computer where it is installed.
In this way, Java is independent from the platform and it will be possible run the same programme, compiled only once on a computer with a compiler, on every hardware platform.
A Java Virtual Machine is implemented even in the browsers in order to run Java programmes found in the net, the so-called Applet.
