No idea what I'm doing wrong. If I could get some help that would be fantastic. Here's the class with the error:
import java.util.Scanner;
/** The solitaire card game Idiot's Delight. */
public class IdiotsDelight {
/** For reading from the console. */
public static final Scanner INPUT = new Scanner(System.in);
/** The four Stacks of Cards. */
private Stack<Card>[] stacks;

private Deck deck;
/** Create and shuffle the Deck. Deal one Card to each Stack. */
public IdiotsDelight() {
deck = new Deck();
deck.shuffle();
stacks = new Stack[4]; // This causes a compiler warning
for (int i = 0; i < 4; i++) {
stacks[i] = new ArrayStack<Card>();
}
deal();
}
/** Deal one Card from the Deck onto each Stack. */
public void deal() {
for (Stack<Card> s : stacks) {
s.push(deck.deal());
}
}
/** Play the game. */
public void play() {
while (true) {
// Print game state
System.out.println("\n" + this);
// Check for victory
boolean done = true;
for (Stack<Card> s : stacks) {
if (!(s.isEmpty())) {
done = false;
break;
}
}
if (done) {
System.out.println("You win!");
return;
}
// Get command
System.out.print("Your command (pair, suit, deal, or quit)? ");
String command = INPUT.nextLine();
// Handle command
if (command.equals("pair")) {
removePair();
} else if (command.equals("suit")) {
removeLowCard();
} else if (command.equals("deal")) {
deal();
} else {
return;
}
}
}
/**

public void removeLowCard() throws IllegalMoveException {
System.out.print("Location (1-4) of low card? ");
int i = INPUT.nextInt();
System.out.print("Location (1-4) of high card? ");
int j = INPUT.nextInt();
INPUT.nextLine(); // To clear out input
stacks[i - 1].pop();
}
/**

public void removePair() throws IllegalMoveException {

stacks[j - 1].pop();
}
public String toString() {
String result = "";
for (int i = 0; i < 4; i++) {
if (stacks[i].isEmpty()) {
result += "-- ";
} else {
result += stacks[i].peek() + " ";
}
}
return result + "\n" + deck.size() + " cards left in the deck";
}
/** Create and play the game. */
public static void main(String[] args) {
System.out.println("Welcome to Idiot's Delight.");
IdiotsDelight game = new IdiotsDelight();
game.play();
}
}
Error is in the play() method, specifically on these 2 lines with the same error:
removePair();
removeLowCard();
IllgalMoveException class just in case it's needed:
/** Thrown when a player attempts an illegal move in a game. */
public class IllegalMoveException extends Exception {
}
