Constructors<\/strong><\/p>\n

Use the debugger to watch how cards are constructed:<\/p>\n

    \n
  1. Set a breakpoint in the WildDrawCard constructor (line 17).<\/li>\n
  2. Create a new WildDrawCard by calling the constructor..<\/li>\n
  3. Use the \u2018step into\u2019 button to step through the code. Observe how the\u00a0super()<\/code> call works.<\/li>\n
  4. Repeat this process for the other kinds of cards.<\/li>\n<\/ol>\n

    Set up a game:<\/p>\n

      \n
    1. Call\u00a0Game.makeStandardDeck()<\/code> to create a deck (ArrayList) of cards.<\/li>\n
    2. Press the\u00a0Get<\/strong> button to save this deck in a variable.<\/li>\n
    3. Call the\u00a0Game<\/code> constructor, providing this deck as a parameter.<\/li>\n
    4. Call the\u00a0deal()<\/code> method on the game you created to deal the cards.<\/li>\n<\/ol>\n

      Inheriting methods<\/strong><\/p>\n

        \n
      1. Create a selection of cards from the different card classes.<\/li>\n
      2. Right-click on each card to observe the methods it implements and the methods it inherits.<\/li>\n
      3. Where is the\u00a0canPlay()<\/code> method implemented on each card type?<\/li>\n
      4. Where is the\u00a0play()<\/code> method implemented on each card type?<\/li>\n
      5. Set a breakpoint in\u00a0WildDrawCard.play()<\/code> (line 26).<\/li>\n
      6. Create a WildDrawCard and call its play() method. Use the debugger to step through the code.<\/li>\n
      7. Observe the order the code is executed.<\/li>\n<\/ol>\n

        Add a new card type<\/strong><\/p>\n

          \n
        1. Change the rule for the NumberCard so it can only be played on another NumberCard of value one more or one less that itself. (i.e. a 5 can be only played on a 4 or 6). Numbers should wrap around, so a 0 can be played on a 9 and vice-versa.<\/li>\n
        2. Create a Transfer card class which transfers 2 random cards from the player to the previous player.<\/li>\n
        3. Add a new Reverse-Draw card class which reverses the direction of play\u00a0then<\/em>causes the next player to draw. Does it have any code in common with other cards? What class would it be best to inherit from?<\/li>\n
        4. Create your own card types.<\/li>\n<\/ol>\n
