Based on the enormous amount of press Java is getting and the amount of excitement it has generated, you may get the impression that Java will save the world-or at least solve all the problems of the Internet. Not so. Java's hype has run far ahead of its capabilities, and while Java is indeed new and interesting, it really is another programming language with which you write programs that run on the Internet. In this respect, Java is closer to popular programming languages such as C, C++, Visual Basic, or Pascal, than it is to a page description language such as HTML, or a very simple scripting language such as JavaScript.
