How can I have this card shuffler non-duplicate? [duplicate]

I made this card shuffler that creates and randomizes a deck of 52. The only problem is that there is no restrictions against randomizing a duplicate card. I was thinking of storing the instance of the card[] into a 2d array like deck[][]. Then the program could check to see if the newly randomized card already exists. The only problem is... I don't really know how to do that. If anyone has a good idea, I would appreciate it.

import java.util.Arrays;

public class cardShuffle {
    public static void main(String[] args) {
        String[] card = new String[2];

        String[] suits = {"♢", "♥", "♤", "♧"};
        String[] faces = {"Ace", "2", "3", "4", "5", "6", "7", "8", "9", "10", "Joker", "Queen", "King"};

        //Randomizes and prints a deck of 52 cards
        for(int i = 0; i < 52; i++){
            card[0] = suits[(int) (Math.random() * 4)];//Picks a random suit
            card[1] = faces[(int) (Math.random() * 13)];//Picks a random face value

            System.out.println(Arrays.toString(card));//Prints the randomized card
        }
    }
}
