8. 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.
