JDK Vs JRE Vs JVM
==============================
JDK (Java Development Kit): A platform that provides tools for developing, testing, and running Java programs.
JRE (Java Runtime Environment): A collection of libraries and software that allows Java programs to run. It's like a engine that powers the Java code. JRE is a part of JDK.
JVM (Java Virtual Machine): A software that runs Java bytecode and manages memory. It's like a virtual engine that executes the Java code. JVM is a part of JRE.
Think of it like a car:
- JDK is the entire car (platform)
- JRE is the engine (libraries and software)
- JVM is the engine's cylinder (executes bytecode and manages memory)
So, JDK > JRE > JVM
