Battleship (UML Diagram)
Battleship is a Java Maven project for a game simulation that uses the following design patterns:
- The Command Pattern
- The Strategy Pattern
- The Factory Pattern
- The Observer Pattern
This Battleship game design allows for dynamically initializing the game board with a different number of ships, and also with different sized board grids. The ships are randomly placed on the player's boards in both horizontal and vertical directions.
Command objects are used to encapsulate these different initialization requests. The JUnit test suite tests for two command objects, one that initializes the player's boards with 3 ships on a 5 x 5 grid, and another that initializes the player's boards with 6 ships on a 10 x 10 grid. Additional command object requests can be easily added by implementing the Command interface.
Used to encapsulate a family of battleship algorithms. By exploiting polymorphism, the game can be initialized with different battleship types for each player. In addition, if an advanced rule was added allowing players to dynamically switch ships during runtime, the Strategy Pattern would make it possible.
Used to create different ship types. The Simple Factory Pattern is used in combination with the Strategy Pattern to allow clients to create different ship types without having to program to a concrete implementation.
Used to notify each player of a winner. When a player fires a winning shot, the Observer Pattern notifies each player by displaying the winning game board to each player. The JUnit test suite for this pattern uses System.out to display two "Winning Game Boards" to the screen, one for each player.
