• The main idea of this homework was to implement the mechanics of a game that is similar with Hearthstone or Gwent. My design idea consists of creating a generic class Card that will be inherited by each specific card (Minions, Environment or Heroes). This thing enables a modular setup, where functionality can be easily added in the future. Therefore, each card type is customizable and can support modifications without affecting the other cards or a new card can be easily created using the template defined in the class.

• Also, I created a class that implements the player's profile. The game consists of two players that perform their actions in turns. Each player has a deck that is specified at the input and is shuffled at the beginning of every game. The players receive a card from the deck when the game starts and when a round ends. To implement this, I created a deep copy of each deck and an array list for the cards that a player has in hand, thus avoiding the need to modify the data received as input. The player class also has some helpful members, for example the frontRow, the backRow or the hasMoved property that I used to simplify the implementation.

• The game is played on a table that I chose to represent as a 4 x 5 matrix that has the type Card. The table is a shared entity between the classes in this project, so I used the Singleton pattern for it because it avoids a global declaration and multiple instances of the same class. Also, all the methods that implement the actions involving the cards of the players are defined inside this Table object, providing flexibility when calling them.

• Finally, I created a class Game that connects the received input with all the things described earlier. Here, I initialized the setup for each game and implemented a parser to be able to execute the received commands. The method performAction() provides this functionality, writing data to the output according to each situation. You can take a look at the diagram below to better understand the relations between the classes that I defined to make this project.

It was a nice project that helped me understand the basics of the Object-Oriented Programming paradigm. After I have successfully finished it, I can say that I am more familiar with concepts like class inheritance, overriding, overloading, encapsulation, etc.
