One essential notion of OOP Java must be understood.  Java offers a secure feature that aids in the development of a virus-free and tamper-proof system for users.  OOP is an abbreviation for Object-Oriented Programming language. OOP denotes that everything in Java is considered an object.  Java is not compiled into a platform-specific machine; rather, it is compiled into platform-independent bytecode. The Virtual Machine that operates the platform interprets this code.
