The JRE is the on-disk part of Java that creates the JVM. The JVM is the Java platform component that executes programs. It's important to differentiate between these three technologies, as well as understanding how they're connected. The JDK includes tools useful for developing and testing. The Java Development Kit (JDK) is one of three core technology packages used in Java programming, along with the JVM (Java Virtual Machine) and the JRE (Java Runtime Environment).
