I've written all the classes but the final class. Game. I've provided attached the project, and the skeleton class.

You'll create the Game class and use the Start method to play a full game of checkers.

You'll ask the user for

1. A piece name

2. X coordinate

3. Y coordinate.

4. Ensure proper eror handling and exception catching (make sure the user is forced to answer the question correctly).

5. Move the piece.

6. Switch turns

7. Continue until the game is over.

All of this functionality is written into the classes, you just need to wire it together.

Below i will list the code provided. I seperated by 7 classes please fill in main. Thank you
