well, Java is a programming language expressly designed for use in the distributed environment of the Internet. It was designed to have the "look and feel" of the C++ language, but it is simpler to use than C++ and enforces an object-oriented programming model. Java can be used to create complete applications that may run on a single computer or be distributed among servers and clients in a network. It can also be used to build a small application module or applet for use as part of a Web page. Applets make it possible for a Web page user to interact with the page.

The major characteristics of Java are:

* The programs you create are portable in a network. (See portability.) Your source program is compiled into what Java calls bytecode, which can be run anywhere in a network on a server or client that has a Java virtual machine. The Java virtual machine interprets the bytecode into code that will run on the real computer hardware. This means that individual computer platform differences such as instruction lengths can be recognized and accommodated locally just as the program is being executed. Platform-specific versions of your program are no longer needed.
* The code is robust, here meaning that, unlike programs written in C++ and perhaps some other languages, the Java objects can contain no references to data external to themselves or other known objects. This ensures that an instruction can not contain the address of data storage in another application or in the operating system itself, either of which would cause the program and perhaps the operating system itself to terminate or "crash." The Java virtual machine makes a number of checks on each object to ensure integrity.

A high-level programming language developed by Sun Microsystems. Java was originally called OAK, and was designed for handheld devices and set-top boxes. Oak was unsuccessful so in 1995 Sun changed the name to Java and modified the language to take advantage of the burgeoning World Wide Web.
Java is an object-oriented language similar to C++, but simplified to eliminate language features that cause common programming errors. Java source code files (files with a .java extension) are compiled into a format called bytecode (files with a .class extension), which can then be executed by a Java interpreter.

* Java is object-oriented, which means that, among other characteristics, an object can take advantage of being part of a class of objects and inherit code that is common to the class. Objects are thought of as "nouns" that a user might relate to rather than the traditional procedural "verbs." A method can be thought of as one of the object's capabilities or behaviors.
* In addition to being executed at the client rather than the server, a Java applet has other characteristics designed to make it run fast.
* Relative to C++, Java is easier to learn. (However, it is not a language you'll pick up in an evening!)

well rakesh Java is a programming language originally developed by Sun Microsystems and released in 1995 as a core component of Sun Microsystems' Java platform. The language derives much of its syntax from C and C++ but has a simpler object model and fewer low-level facilities. Java applications are typically compiled to bytecode that can run on any Java virtual machine (JVM) regardless of computer architecture.

The original and reference implementation Java compilers, virtual machines, and class libraries were developed by Sun from 1995. As of May 2007, in compliance with the specifications of the Java Community Process, Sun made available most of their Java technologies as free software under the GNU General Public License. Others have also developed alternative implementations of these Sun technologies, such as the GNU Compiler for Java and GNU Classpath.

If you want to learn it buy some good books from the market and practice programs as much as you can.

You can use internet for learning it.
There are some very good tutorials available on Net.

WELL;
Java allows you to play online games, chat with people around the world, calculate your mortgage interest, and view images in 3D, just to name a few. It's also integral to the intranet applications and other e-business solutions that are the foundation of corporate computing.

ava is a technology that allows software designed and written just once for an idealized "virtual machine" to run on a variety of real computers, including Windows PCs, Macintoshes, and Unix computers. On the web, Java is quite popular on web servers, used "under the hood" by many of the largest interactive websites. Here it serves the same role that PHP, ASP or Perl might, although traditionally Java has been used for larger-scale projects.

Java can also be used to create small programs, known as "applets," to be embedded in web pages. For instance, a web page using Java could contain an interactive weather map, a live display of subway trains, or a video game, without the need for the web server to do all of the work. Unlike normal software such as .EXE files, these "applets" can not access or delete your personal files unless they ask for and are given express permission to do so. In the real world, users hardly ever give permission for this, so applets generally don't ask.

As of this writing, Java is usually (though not always) included as standard equipment on Windows PCs. If you choose to use Java applets on your site, you can invite your users to download the Java plug-in from Sun's website, using the "Get It Now" button on that site.
