feat: Implement 2D array input and output using nested loops and enhanced for-each loop

🧠 Logic:
- Declares and initializes a 3x3 2D array.
- Takes input using nested `for` loops for each cell.
- Outputs each row using `Arrays.toString()` via enhanced for-each loop for cleaner display.

🔍 Highlights fixed-size matrix input, row-wise traversal, and formatted output.
