ช่วยเขียนหน่อยค่ะ java เนื้อ หา อยู่ข้างในนะค่ะ ด่วนๆๆ

public class Deck {
		    public static void main(String[] args) {
		        String[] suit = { "Club", "Diamond", "Heart", "Spade" };
		        String[] rank = { "2", "3", "4", "5", "6", "7", "8", "9", "10", "J", "Q", "K", "A" };

		        // avoid hardwired constants
		        int SUITS = suit.length;
		        int RANKS = rank.length;
		        int N = SUITS * RANKS;

		        // initialize deck
		        String[] deck = new String[N];
		        for (int i = 0; i < RANKS; i++) {
		            for (int j = 0; j < SUITS; j++) {
		                deck[SUITS*i + j] = rank[i] + " " + suit[j];
		            }
		        }

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

		        // print shuffled deck
		        for (int i = 0; i < N; i++) {
		            System.out.println(deck[i]);
		        }
		    }
