"Java is a programming language and computing platform first released by Sun Microsystems in 1995. There are lots of applications and websites that will not work unless you have Java installed, and more are created every day. Java is fast, secure, realiable. From laptops to datacenters, game consoles to scientific supercomputers, cell phones to the Internet, Java is everywhere!"

Java is object-oriented. What does that mean? Unlike languages, such as FORTRAN, which focus on giving the computer imperative "Do this/Do that" commands, object-oriented languages focus on data. Of course, object-oriented programs still tell the computer what to do. They start, however, by organizing the data, and the commands come later.
