Vara,
The JVM (java virtual machine) runs java .class files, aka bytecodes. The JRE (java runtime environment) contains a JVM. The JDK (java development kit) contains a JVM and a compiler.

Hi Varad,

In other words:

JVM (Java virtual Machine): The program that executes java programs (actually java's bytecode).

JRE (Java Runtime Environement): The kit that is to be installed on a computer to RUN java programs. The JRE containts mainly a JVM and Java standard librairies.

JDK (Java developement Kit): The kit that is to be installed on a computer to DEVELOP java programs.

I hope that will definitely clarify all this acronyms !
