Java Virtual Machine (JVM)

 Java Virtual Machine  (JVM) 

Definition :-The java compiler produces an intermedia code known as bytecode for machine that does not exist.  This machine is called the Java Virtual Machine  and it exists only inside the computer memory.


->It is simulated computer within the computer and does all major function of a real computer.

Thr process of compiling a java program into bytecode which is known as Virtual machine code.

->The Virtual machine code is not machine specific.

->The machine Specific code(known as machine code) is generated by the Java interpreter by acting as an intermediary between the virtual machine and the real machine.

->Remember that the interpreter is different for different.

>The Java object frame work (java API) acts as the intermediary between the user programs and the virtual machine which in turns acts as the intermediary between the operating system and Java object frame work.
