    What is difference between JVM, JDK and JRE

    JVM
    JVM is an acronym for Java Virtual Machine, it is an abstract machine which provides the runtime environment in which java bytecode can be executed.
    JVMs are available for many hardware and software platforms (so JVM is plateform dependent).

    JRE
    JRE stands for Java Runtime Environment. It is the implementation of JVM and physically exists.

    JDK
    JDK is an acronym for Java Development Kit. It physically exists. It contains JRE + development tools.
