Difference between JVM, JRE & JDK

In this video, we will be discussing the difference between JDK, JRE & JVM. But before getting into the details let us discuss them in brief first.

1) JDK (Java Development Kit) is a Kit that provides the environment to develop and execute(run) the Java program. JDK is a kit(or package) that includes two things

- Development Tools(to provide an environment to develop your java programs)

- JRE (to execute your java program).

 2) JRE (Java Runtime Environment) is an installation package that provides an environment to only run(not develop) the java program (or application) onto your machine. JRE is only used by those who only want to run Java programs that are end-users of your system.

 3) JVM (Java Virtual Machine) is a very important part of both JDK and JRE because it is contained or inbuilt in both. Whatever Java program you run using JRE or JDK goes into JVM and JVM is responsible for executing the java program line by line, hence it is also known as an interpreter.

Watch the video till the end to know the difference between JDK, JRE & JVM in detail.
