Java is created to operate in the distributed environment on the net. It is much easier to use compared to C++. Java functions are based on the object-oriented programming model. You can use it for online video, audio, games, banking applications and chat. It is also used in various intranet applications.

Microsoft Java was first developed for Internet Explorer 3. This was the fastest implementation of JVM (Java Virtual Machine) for the first couple of years after Java release. The creator of Java, Sun Microsystems, sued Microsoft for incomplete implementation of Java 1.1 standard. Microsoft stopped Java implementation and settled the lawsuit.

Service Pack 1 for XP from 2002 came with Microsoft Java VM. However, in 2003, Microsoft released SP1a without Java VM.
