feat: Demonstrate behavior of static and non-static variables across method calls

🧠 Logic:
- `static int a = 10;` is shared across all instances of the class.
- `int b = 10;` is re-initialized every time `fun()` is called.
- On each call to `fun()`:
  - `a` retains and increments its value.
  - `b` resets to 10, increments to 11, but the new value doesn't persist.
