Question

Java programing

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

• The program should be doing 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

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

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

Face of cards in each Hand

Hand 1:

      Clubs: 8 1 7 2 Q 3 4

      Diamonds: 5 K 9
