Pass By Value With Reference Types

💡 Java Memory Tip: "Objects are passed by reference"... RIGHT? Wrong!

A huge misconception in Java is how objects are passed to methods. Let's clear it up: Everything in Java is Pass-by-Value. Everything.

When you pass an Object to a method, you are NOT passing the object itself. You are passing a copy of the reference (the memory address).

📺 Think of it like a TV and a remote control: The Object (the TV) lives in the Heap memory. Your variable in the Stack is just a remote control. When you pass it to a method, Java makes a photocopy of your remote. Now you have two remotes pointing to the SAME TV. If the method uses its remote to change the channel, your original remote will see the new channel too!

Don't believe me? I've set up an interactive execution. Click the link, step through the code, and watch how the Stack and Heap interact in real-time 👇
