feat: Demonstrate basic usage of ArrayList with user input in Java

🧠 Logic:
- Creates an `ArrayList<Integer>` with initial capacity of 5.
- Takes 5 user inputs and stores them in the list using `add()`.
- Prints each element using `get(index)` since array-style indexing doesn't apply to ArrayList.
- Shows example usages (commented): `contains()`, `set()`, `remove()`, and printing the list.
