I am creating a game of Set with Java. It requires multiple classes/methods which I will paste below. But my two specific questions revolve around the "Game" and "GameText" classes.

1. When I print the ArrayList of Selected BaordSquares (the function "list selected") it is returning to me a value such as [BoardSquare@3d4eac69] rather than the value of the card, how do I fix this to print the card?

2. I am getting an issue with the line of code in the TestSelected method BoardSquare bs2 = selected.get(1); where it says "Exception in thread "main" java.lang.IndexOutOfBoundsException: Index: 1, Size: 1" how do I fix this?

Game class

import java.util.ArrayList;

public class Game{ //intialize variable, deck and board, arraylist private int selectedCards; private Deck deck; private Board board; private ArrayList selected;

/* Constructor creates a new game with a new shuffled deck and board, selected starts empty */ public Game(){ selectedCards = 0; deck = new Deck(); deck.shuffle(); board = new Board(deck); selected = new ArrayList(3); }

/* method outOfCards determines if the board is out of new cards @return boolean out */ public boolean outOfCards(){ boolean out; if(deck.isEmpty() == true){ out = true; } else { out = false; } return out; } /* method addToSelected takes the BoardSquare the user selects and saves it to compare later @param row @param column */ public void addToSelected(int row, int col){ //add card to an arraylist of selected selected.add(board.getBoardSquare(row, col)); selectedCards++; if (selectedCards == 3){ testSelected(); } } /* method numSelected returns the number of selected cards being held @return selectedCards */ public int numSelected(){ return selectedCards; } /* method testSelected tests whether the three cards in the selected ArrayList are a Set */ public void testSelected(){ //test if the cards from selected are a Set, method is in Card Class BoardSquare bs1 = selected.get(0); BoardSquare bs2 = selected.get(1); BoardSquare bs3 = selected.get(2); //Card.isSet(bs1.getCard(), bs2.getCard(), bs2.getCard()); if (Card.isSet(bs1.getCard(), bs2.getCard(), bs3.getCard())){ board.replaceCard(deck.getTopCard(), bs1.getRow(), bs1.getColumn()); board.replaceCard(deck.getTopCard(), bs2.getRow(), bs2.getColumn()); board.replaceCard(deck.getTopCard(), bs3.getRow(), bs3.getColumn()); //print SET System.out.print("It's a SET "); //empty ArrayList for (int i = 0; i < selected.size(); i++) { selected.remove(i); } } else{ //print NOT a SET System.out.print("Not a SET "); //empty ArrayList for (int i = 0; i < selected.size(); i++) { selected.remove(i); } } } /* method removeSelected de-selects a boardsquare from the arraylist @param row @param column */ public void removeSelected(int row, int col){ boolean status = false; if (selected.get(0).getRow() == row && selected.get(0).getColumn() == col){ selected.remove(0); selectedCards--; } else if (selected.get(1).getRow() == row && selected.get(1).getColumn() == col){ selected.remove(1); selectedCards--; } else if (selected.get(2).getRow() == row && selected.get(2).getColumn() == col){ selected.remove(2); selectedCards--; } else{ status = false; } } /* method getSelected returns the cards that have been selected @return selected */ public ArrayList getSelected(){ return selected; } /* method add3 adds three cards to the board */ public void add3(){ board.add3(deck); } /* method to String converts the game to a string for printing */ public String toString(){ return board.toString(); }

Game Text

"); row = keyboard.nextInt(); col = keyboard.nextInt(); g.addToSelected(row,col); System.out.println(g.getSelected()); // if it's the 3rd card selected if (g.numSelected() == 3) { // is it a set? // if it is a set, the cards are replaced // if it is NOT a set, all selected cards are unselected g.testSelected(); // re-display board System.out.println(g); } } // unselect else if (input.equalsIgnoreCase("u")) { System.out.print("row col ?
