**Your First Java Program + JDK, JRE & JVM Explained**

In this video, we take the next step in Java and understand how a Java program actually works — from writing your first `Hello World` program to running it using the JVM.

### In this video:

• What is JDK?
• What is JRE?
• What is JVM?
• JDK vs JRE vs JVM
• What is Java SE, Java EE and Java ME?
• What is Bytecode?
• How Java achieves platform independence
• Writing your first Java program
• Compiling Java code using `javac`
• Running Java bytecode using the JVM

The goal is simple: **understand what happens behind your first Java program**, instead of just memorizing commands.

This is **Lecture #2** of the Java Full Course by **Backend EZY**.

If you’re learning Java from scratch, follow the lectures in order and build your fundamentals step by step.
