Design a Chess Game

Problem Statement: The problem is to design a Chess Game using Object Oriented Principles. Asked In: Adobe, Amazon, Microsoft, etc. Solution: These type of questions are asked in interviews to Judge the Object-Oriented Design skill of a candidate. So, first of all we should think about the classes. The main classes will be:

1. Spot: A spot represents one block of the 8x8 grid and an optional piece.
2. Piece: The basic building block of the system, every piece will be placed on a spot. Piece class is an abstract class. The extended classes (Pawn, King, Queen, Rook, Knight, Bishop) implements the abstracted operations.
3. Board: Board is an 8x8 set of boxes containing all active chess pieces.
4. Player: Player class represents one of the participants playing the game.
5. Move: Represents a game move, containing the starting and ending spot. The Move class will also keep track of the player who made the move.
6. Game: This class controls the flow of a game. It keeps track of all the game moves, which player has the current turn, and the final result of the game.
Let's look at the details. These codes are self-explanatory. You can have a look at the properties/variables and methods of different classes. Spot: To represent a cell on the chess board: Piece: An abstract class to represent common functionality of all chess pieces: King: To represent King as a chess piece: Knight: To represent Knight as a chess piece Similarly, we can create classes for other pieces like Queen, Pawns, Rooks, Bishops etc. Board: To represent a chess board: Player: An abstract class for player, it can be a human or a computer. Move: To represent a chess move: Game: To represent a chess game: Reference: https://massivetechinterview.blogspot.com/2015/07/design-chess-game-using-oo-principles.html
