Unique random numbers using Math.Random and Modulus

Help, I am to Use Math.random()and the remainder operator to generate 52 distinct numbers from 0 to 51. These numbers will represent a deck of card and let’s call it deckOfCard. (Now you have a one-dimensional array of size 52.) For this step, you should write a method called generateCardwhich returns nothing but accepts one argument which is the array variable that represents the deck of card(pass by value). For the output, I am trying to get UNIQUE random numbers.

public class Decks {

public static void main(String[] args) {

    generate();

}

public static void generate() {
    int deckOfCard[] = new int[52];

    for (int counts = 0; counts < 52; counts++) {

        deckOfCard[counts] = (int) (Math.random() * 51);

    }

    for (int count = 0; count < deckOfCard.length; count++) {

        System.out.print("\t" + deckOfCard[count]);

    }

}
}
