In this video, we will discuss an important definition of JVM, JRE, and JDK in the Java programming language. We also discuss the difference between JVM, JRE, and JDK.

The JDK(Java Development Kit) is a superset of the JRE and contains everything that is in the JRE, plus tools such as the compiler, debugger, JavaDoc, keytool etc necessary for developing and running Java programs or applications.

JVM is a very important component of Java programming language. When you run the Java program, the Java compiler first compiles your Java code to bytecode. Then, the JVM translates bytecode into native machine code (set of instructions that a computer’s CPU executes directly).

The Java Runtime Environment (JRE) provides the libraries, the Java Virtual Machine, and other components to run applets and applications written in the Java programming language.
