Running Linux, 5th Edition

Java

Java is a network-aware, object-oriented language developed by Sun Microsystems. Java originally engendered a lot of excitement in the computing community because it strived to provide a secure language for running applets downloaded from the World Wide Web. The idea was simple: allow web browsers to download Java applets, which run on the client's machine. Many popular Web browsers—including Mozilla and Firefox, the GNOME variant Galeon, and the KDE web browser Konqueror (see Chapter 5)--include support for Java. Furthermore, the Java Developer's Kit and other tools have been ported to Linux.

But Java proved suitable for more than applets. It has been used more and more as a general-purpose programming language that offers fewer obstacles for beginners than other languages. Because of its built-in networking libraries, it is often used for programming client/server applications. A number of schools also choose it nowadays for programming courses.

The Promise of Java, or Why You Might Want to Use Java

All this may not sound too exciting to you. There are lots of object-oriented programming languages, after all, and with Mozilla plug-ins you can download executable programs from web servers and execute them on your local machine.

But Java is more than just an object-oriented programming language. One of its most exciting aspects is platform independence . That means you can write and compile your Java program and then deploy it on almost every machine, whether it is a lowly '386 ...
