How Java Code Actually Runs! ⚙️🔥

Step 1: Write Code
Hello.java (human-readable)

Step 2: Compile
javac Hello.java
Creates Hello.class (bytecode) ✨

Step 3: JVM Reads Bytecode
Java Virtual Machine loads .class file

Step 4: JVM to Machine Code
JVM converts bytecode to machine code

Step 5: CPU Executes
Your program runs! 💡

The Process:
Source Code → Compiler → Bytecode → JVM → Machine Code → Execution 🎯

Why bytecode?
✅ Write once, run anywhere
✅ Platform independent
✅ Security layer
✅ Optimization possible

Bytecode is NOT machine code!
It's intermediate code for JVM

That's why Java is portable! 🚀

Compile then run! 💪
