Bytecode and JVM in Java

- Bytecode may be defined as a highly optimized set of instructions
  designed to be executed by java run time system.

- JVM may be refered to as the interpreter for bytecode.

- Translating a java's program into bytecode helps make it easier to    run in a wide variety of environment as only JVM needs to be          implemented.

-  But remember , the details of the JVM will differ from platform 
   to platform , all interpret the same java bytecode.

- If program was compiled to native code  , then different versions     of same program would have to exist for each type of CPU               connected to the internet , which is not feasible.

- So this hepls in creating portable programs.
