JVM

JVM (Java Virtual Machine) is a subjective machine. It is a requirement that provides runtime environment in which java bytecode can be implemented.

JVMs are available for many application and components techniques. JVM, JRE and JDK are system reliant because settings of each OS varies. But, Java is system separate.

JRE

JRE means for Java Runtime Environment.It is used to give runtime environment.It is the execution of JVM.It actually prevails.It contains set of collections + other information that JVM uses at runtime.

Implementation of JVMs are also definitely launched by other organizations besides Sun Small Systems.

JDK

The Java Development Kit (JDK) is an execution of either one of the Java System, Standard Version, Java System, Business Version or Java System, Small Version platforms launched by Oracle Organization in the form of a binary product targeted at Java designers on Solaris, A linux systemunix, Mac OS X or Windows.
