Creating a version of the card game SET in Java, using classes Card, Triad, Group, Deck, and Simulation. Below I have the classes Card, Triad, Deck, and Group but I'm having trouble with the Simulation class and looking for some help. In my version the Simulation class is the main method and 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. In the card game a SET is defined as a set if with respect to each of the four attributes, the cards are either all the same or all dierent. For Example: First Card is one green oval with a solid shading, Second Card has two green ovals with solid shading and the Third Card has three green ovals with solid shading, all cards have the same shape (ovals), the same color (green), and the same shading (solid), and each card has a dierent number of ovals. If that Third Card was three green squiggles with solid shading it wouldn't be a set because the shape wasn't an oval.

public class Card

{ //public enum declarations public enum Shape{Oval, Squiggle, Diamond}; public enum Shading{Solid, Striped, Outlined}; public enum Number{One, Two, Three}; public enum Color{Red, Green, Purple}

// class number variable declaration Shading shading; Color color; Shape shape; Number number; //Constructor public Card(Shape shape, Color color, Shading shading, Number number) { this.shape = shape; this.color = color; this.shading = shading; this.number = number; }

public Shading getShading() { return shading; } public Shape getShape() { return shape; } public Color getColor() { return color; } public Number getNumber() { return number; } @Override public String toString() { String cardString = ""; cardString += shape +" "; cardString += color +" "; cardString += shading +" "; cardString += number; return cardString; } } ***************************************************************
