A network-oriented programming language developed by Sun Microsystems. It was specifically designed for writing scripts, or programs, that can be safely downloaded to any type of computer through the Internet and immediately run without the fear of viruses or other damage to your computer. By making use of small Java programs (called "Applets"), webpages can include functions such as calculators, animations, and interactive games. In spite of the similarity in name to JavaScript, it is not closely related to JavaScript.
