What is Java?

A very portable object-oriented programming language.

A large supporting class library that covers many general needs.

Can creates Applets, Applications, Servlets, JavaServer Pages, and more.

An open standard - the language specification is publicly available.

Java is the most popular server technology today.

Much of the syntax of Java is the same as C and C++. One major difference is that Java does not have pointers. However, the biggest difference is that you must write object oriented code in Java. Procedural pieces of code can only be embedded in objects.

In Java we distinguish between applications, which are programs that perform the same functions as those written in other programming languages, and applets, which are programs that can be embedded in a Web page and accessed over the Internet. When a program is compiled, a byte code is produced that can be read and executed by any platform that can run Java.
