JDK vs JRE vs JVM Explained | CPU, Computer, Workstation Analogy | Java Basics Welcome to Tech ఆరంభం! Are you confused about the core differences between *JDK, JRE, and JVM**? You are not alone! This is one of the most frequently asked **Java interview questions* and a major stumbling block for Java beginners. In this simple and highly effective video, we break down the complex relationship between the three components of the Java platform. We use the famous *CPU, Computer, and Development Workstation analogy* to make the differences crystal clear. Watch the full video to understand: *JVM (Java Virtual Machine):* The abstract machine that executes Bytecode (Analogy: CPU). *JRE (Java Runtime Environment):* Everything needed to run a Java program (Analogy: Computer System). *JDK (Java Development Kit):* The full set of tools for developing, debugging, and executing Java code (Analogy: Development Workstation). VIDEO TIMESTAMPS (For Easy Navigation): 0:00 - Introduction to the Confusion 0:18 - What is JVM (Java Virtual Machine)? 0:57 - What is JRE (Java Runtime Environment)? 1:39 - What is JDK (Java Development Kit)? 2:17 - Final Simple Analogy Summary (CPU, Computer, Workstation) FAQs: What is the difference between JDK and JRE? JDK is for development (writing/compiling code), and JRE is for running code. What is the use of JVM? JVM translates Java Bytecode into native machine code and manages memory. Do I need JDK to run a Java program? No, you only need JRE to run a Java program. You need JDK only if you are developing or compiling Java code.
