Java is a high level, robust, secured and object-oriented programming language. There are many key differneces while comparing java with other languages. Code in C, C++ is first translated into specific type of native machine. The Java compiler instead turns code into something called Bytecode, which is then interpreted by software called the Java Runtime Environment (JRE) or JVM. With this we get the advantage of Write Once, Run Anywhere(WORA). Other features like Portability, Architectue-Neutral, Security, OOP's, etc. Java is not just considerd but also used in developing many large  distributed, enterprise applications. Java is, arguably, one of the most popular programming languages amongst developers and is used to create web applications, customized software and web portals, including eCommerce and m-Commerce solutions. A lot of technologies grouped in J2EE, that covers many the aspects of enterprise programming - servlets, jsp, ejb, jdbc to access the database, etc.
