Java Runtime Environment Difference between JDK, JRE and JVM Understanding the difference between JDK, JRE and JVM is important in Java JDK JRE JVM Java Development Kit JDK is an acronym for Java Development Kit. It physically exists. It contains JRE + development tools. Java Runtime Environment JRE is used to provide runtime environment. It is the implementation of JVM. It physically exists. Java Virtual Machine JVM is an abstract machine. It is a specification that provides runtime environment in which java bytecode can be executed.
