Difference Between JDK JRE and JVM: A Comprehensive Guide

The terms JDK JRE and JVM are all related to Java, but they serve different purposes.

The Java Development Kit (JDK) is a software development kit that contains tools for developing Java applications.

You need the JRE when you just want to run Java applications, but don’t need to develop them

The JVM is always needed when you are running a Java program, as it is the engine that executes the program’s bytecode.

The Java Virtual Machine is responsible for running Java bytecode.
