Java is the most prevalent programming language in the world today. It was originally developed by Sun Microsystems, which has now merged with Oracle Corporation. Java is a platform independent application language because, if a Java code runs on one platform, it does not need to be recompiled to run on another. It follows “Write Once, Run Anywhere” (WORA) paradigm. Java is one of the most popular programming languages in use, particularly for client-server web applications. It allows you to work and play in a secure computing environment. Applications developed in Java on a Windows platform are also compatible with Macintosh. Java allows you to play online games, chat with people around the world, calculate your mortgage interest, and view images in 3D.
