First and foremost, Java is a programming language - not a magic elixir - a programming language.
It is used to write application programs, mostly, although SUN wants to push JAVA for operating systems so that perhaps SUN can monopolize the OS market instead of Microsoft - envy and jealousy go a long way with Scott McGreedy.
Java's mantra of a universal language - "Write one, run everywhere" (sometimes referred to as "Write once, Crash Everywhere") - lends itself useful to some applications, notably small routines that run on various web sites.
I am encountering more and more of these as time goes on - ON THE WEB/INTERNET.
Thus, there does seem to be some level of usefulness for WEB-BASED applications.
By virtue of Java being slow (it is an "interpreted language" in its original incarnation), it taxes the processing speed of whatever machine it runs on. Consequently, Java is a BOON for Intel processors !
