Question

Dealing Cards

Write a program that deals a deck of card into 4 hands – Each hand having 13 cards.

• Your program should do the followings
  • use an array to randomly select 52 cards and deal it into 4 hands.
  • Print each hand unsorted
  • Identify the face value of each hand and display it.
  • You should create a class called Card, and all the methods should be defined within the card class.

Hints – Import below java utility to use the random function.

import java.util.*;

Random rand = new Random();

int r = rand.nextInt(52); // this will generate random numbers between 0-52

to get a value between 1-13, use the mod function and get the remainder

if your number is 15, 15%13 has a remainder of 2. 2 is your face card.

---------------------------------------------------------------------------

11 = jack

12= Queen

13= King

Card is a CLUB - If your generated number is between (1-13)

Card is a Diamond - If your generated number is between (14-26)

Card is a Spade - If your generated number is between (27-39)

Card is a Heart - If your generated number is between (40-52)

Your program output should look like this below

Deck of cards shuffled into 4 hands

8 1 7 18 43 26 31 2 12 3 40 22 4

29 9 10 11 5 35 47 36 25 14 17 39 23

Face of cards in each Hand

Hand 1:

       Clubs: 8 1 7 2 Q 3 4

       Diamonds: 5 K 9

       Spades: 5

       Heart: 4 1

Hand 2:

       Clubs: 4 9 10 J 5

       Diamonds: Q 1 4

       Spades: 3 9 10 K

       Heart: 8

Hand 3:

       Clubs: 6 K

       Diamonds: 10 8 J 3

       Spades: K Q 1 6

       Heart: K 7 9

Hand 4:

       Clubs: K

       Diamonds: 7 2

       Spades: J 8 2 4

Please use below code:

=======================Card.java====================

    private int[] deck = new int[52];

    //string array for Ranks, 13 index would be 0 when take modulus so It is K.
