Read 2 Min Only Most asked Interview Question ============================== 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
