Class CardTable

java.lang.Object
cs171a2.CardTable
All Implemented Interfaces:
Table<Card,CardPlayer>
public class CardTable extends Object implements Table<Card,CardPlayer>
This class represents a table where a game is being played. It implements the Table interface and is designed to work with Card and CardPlayer objects.

Each table instance must keep track of the cards that players place on the table during the game. The number of places available has a fixed size (NUMBER_OF_PLACES), so we use a regular Java array to represent a CardTable's places field. Each entry in this places array contains the cards that were added to that place, which is a more dynamic structure (we don't know in advance how many cards will be added to this place!).

Therefore, each place entry in this array will reference an ArrayList of Card objects.

Here is how to declare the array of ArrayLists field places:

private ArrayList<Card>[] places = new ArrayList[NUMBER_OF_PLACES];

Note that the Field Summary section below will only show you public fields, but you must declare the required field places described above, which is private. You are also free to create additional fields in your class implementation, if deemed necessary.
