feat: Demonstrate array length property and default toString output of arrays

🧠 Logic:
- Declares and initializes integer array `B` and float array `C`.
- Prints `B.length` to show how to retrieve array size.
- Prints `B` and `C` directly, which outputs their reference info (not contents) due to default toString().
- Highlights the difference between printing array contents vs. reference in Java.
