Difference between JVM , JRE , JDK

JVM : Have you ever seen a software to install JVM ? NO ... Because you cant install it . Its considered to be subpart of JRE. Engineers at sun say its hypothetical Java engine that reads and run byte code.

JRE : = JVM + everything needed to run java program ( or should i say class file )

JDK : = JRE + extra tools needed to make java progran. see figure below.
