Trying to use indexOf for this shuffling code

[Eveeen]

So, I have this code and I'm trying to use an indexOf to find a specific card of the deck but every time I try I keep getting an error. Any ideas?




public class Cards {
public static void main(String[] args) {
int Shuffles = Integer.parseIn t(args[0]);
int Evaluation = Integer.parseIn t(args[1]);

String[] SUITS = {
"Clubs", "Diamonds", "Hearts", "Spades"
};

String[] RANKS = {
"2", "3", "4", "5", "6", "7", "8", "9", "10",
"Jack", "Queen", "King", "Ace"
};


int n = SUITS.length * RANKS.length;

if (Shuffles > 5)
throw new RuntimeExceptio n("Maximum of 5 shuffles");

// initialize deck
String[] deck = new String[n];
for (int i = 0; i < RANKS.length; i++) {
for (int j = 0; j < SUITS.length; j++) {
deck[SUITS.length*i + j] = RANKS[i] + " of " + SUITS[j];
}
}

String temp ="";
// shuffle
for (int i = 0; i < n; i++) {
int r = i + (int) (Math.random() * (n-i));
temp = deck[r];
deck[r] = deck[i];
deck[i] = temp;
}



// print shuffled deck
if (Shuffles == 1)
System.out.prin tln("Shuffling " + Shuffles + " time.");
else
System.out.prin tln("Shuffling " + Shuffles + " times.");

System.out.prin tln(deck[Evaluation]);
deck[Evaluation] = deck[Evaluation];

System.out.prin tln();
System.out.prin tln("Starting position: 0");



for (int q = 1; q <= Shuffles; q++) {
for (int i = 0; i < n; i++) {
int r = i + (int) (Math.random() * (n-i));
temp = deck[r];
deck[r] = deck[i];
deck[i] = temp;


}

System.out.prin tln("Shuffle " +q+ ":" + deck.indexOf(de ck[Evaluation]));
}
}
}

      deck[i] = temp;
    }

    // print shuffled deck
    if (Shuffles == 1)
      System.out.println("Shuffling " + Shuffles + " time.");

    System.out.println(deck[Evaluation]);
    deck[Evaluation] = deck[Evaluation];

    System.out.println();
    System.out.println("Starting position: 0");

    for (int q = 1; q <= Shuffles; q++) {
      for (int i = 0; i < n; i++) {
        int r = i + (int)(Math.random() * (n - i));
        temp = deck[r];
        deck[r] = deck[i];
        deck[i] = temp;

      }

      System.out.println("Shuffle " + q + ":" + deck.indexOf(deck[Evaluation]));
    }
  }
}

indexOf is not called using the reference of a String object.
