Creating a version of the card game SET in Java, using classes Card, Triad, Group, Deck, and Simulation. I have the Card and Triad classes created already(below) but I need the other 3. Just need a simple Deck class to shuffle and deal 12 random cards out in groups of 4 based on the attributes of the cards - number, shading, color, and shape and each attribute assumes one of three possible values, Number: { One, Two, Three } Shading: { Solid, Striped, Outlined } Color: { Red, Green, Purple } Shape: { Ovals, Squiggles, Diamonds }. Example: Oval Striped Green 2, Squiggles Solid Purple 3, Diamonds Outlined Red 1, Squiggles Striped Red 2. The Deck class should extend Group, the Group class should implement Iterable interface and is created to show how many sets were created, so you have Triad class that should tell the user if the dealt cards either is or is not a SET and you have the Group class that returns below that says number of SETS made. The Simulation class is the main method and is the only class with a static method. This class should allow the user to input a number of cards to deal, and after dealing out that number of cards 10,000 times print how many times there was at least one set and what was the average number of sets dealt. Mainly having trouble with the Group and Simulation classes any help would be appreciated.
