Static: The Shared Memory Lab

Visualize how static variables exist outside individual objects. Build a global user counter and see how it updates across the entire system.

The Heap (Objects)

No objects in memory. The heap is empty.

Method Area (Static)

User.totalCount
0

This variable belongs to the Class, not any specific object. It is shared across all instances.

Every time you run new User(), the shared static variable increments.

🌎 Static Variables: Think of them as "Global" to the class. They don't live in the individual objects; they live in a special memory area shared by everyone.

Hands-on Labs

Practical exercises to master the concepts.
