Problem:

You are creating a card game where you will ask the user to select a suit where

Suit> 1=Hearts, 2=Diamonds, 3=Clubs, 4=Spades

The objective is for you to fill the users hand with 5 unique cards of the suit that they selected.

To make this happen you will need to create a class called Hand

Hand will consist of the following:

An instance variable: suit

An instance variable: card

A constructor method that sets suit = 4 and card = 13

Code that imports java.util.Random and creates a Random object for use in the methods below

A drawSuit method that returns a randomly generated integer from 1 to 4 using the suit instance variable to generate the range for your random integer

A drawCard method that returns a randomly generated integer from 2 to 14 using the card instance variable to generate the range for your random integer

(2=2, 3=3,….10=10, 11=jack,12=queen,13=king,14=ace)

Explanation / Answer

below is your code: -

Hand.java

//Note That I have overridden equal and hashcode here because I need to insert distinct cards only and to compare

//two cards, equal and hashcode is overridden

import java.util.Random;

public class Hand {
   private int suit;
   private int card;

   Hand() {
       this.suit = 4;
       this.card = 13;
   }

   public int getSuit() {
       return suit;
   }

   public void setSuit(int suit) {
       this.suit = suit;
   }

   public int getCard() {
       return card;
   }

   public void setCard(int card) {
       this.card = card;
   }
  
   public int drawSuit() {
       Random rand = new Random();
       int suitSelected = rand.nextInt(4 - 1 + 1) + 1; // selecting random
                                                       // from 1 to 4
       return suitSelected;
   }
   public int drawCard() {
       Random rand = new Random();
       int cardSelected = rand.nextInt(14 - 2 + 1) + 2; // selecting random
                                                       // from 2 to 14
       return cardSelected;
   }
   public void printCardDetails() {
       String cardS = "", suitS = "";
       for (int i = 2; i <= 14; i++) {
           if (this.card == i) {
               if (i == 11) {
                   cardS = "jack";
               } else if (i == 12) {
                   cardS = "queen";
               } else if (i == 13) {
                   cardS = "king";
               } else if (i == 14) {
                   cardS = "ace";
               } else {
                   cardS = i + "";
               }
           }
       }
      
       for (int i = 1; i <= 4; i++) {
           if (this.suit == i) {
               if (i == 1) {
                   suitS = "Hearts";
               } else if (i == 2) {
                   suitS = "Diamonds";
               } else if (i == 3) {
                   suitS = "Clubs";
               } else if (i == 4) {
                   suitS = "Spades";
               }
           }
       }
      
       System.out.println("Card: "+cardS+" of "+suitS);

   }

   @Override
   public int hashCode() {
       final int prime = 31;
       int result = 1;
       result = prime * result + card;
       result = prime * result + suit;
       return result;
   }

   @Override
   public boolean equals(Object obj) {
       if (this == obj)
           return true;
       if (obj == null)
           return false;
       if (getClass() != obj.getClass())
           return false;
       Hand other = (Hand) obj;
       if (card != other.card)
           return false;
       if (suit != other.suit)
           return false;
       return true;
   }
  
  
}

Driver.java

import java.util.ArrayList;
import java.util.Iterator;
import java.util.Scanner;

public class Driver {
   public static void main(String[] args) {
       Scanner sc = new Scanner(System.in);
       System.out.println("Please select the suit: 1=Hearts, 2=Diamonds, 3=Clubs, 4=Spades.:");
       int suitSelected = sc.nextInt();

       while (suitSelected <= 1 && suitSelected >= 4) { // to check if suit selected is valid.
           suitSelected = sc.nextInt();
       }
       sc.close();
       ArrayList<Hand> hand = new ArrayList<>();
       Hand h;
       int cardSelected;
       for (int i = 0; i < 5; i++) {
           h = new Hand();
           cardSelected =h.drawCard();
           h.setCard(cardSelected);
           h.setSuit(suitSelected);
           while(hand.contains(h)) { // to insert distinct card always, check if card is already present.
               cardSelected =h.drawCard();
               h.setCard(cardSelected);
               h.setSuit(suitSelected);
           }
           hand.add(h);
       }
       System.out.println("Current Hand:");
       showHands(hand);// print current hand details.
      
      
   }
  
   //method to print the current hand.
   public static void showHands(ArrayList<Hand> hand) {
       Iterator<Hand> i = hand.iterator();
       Hand h;
       while(i.hasNext()) {// If hand has still a card
           h = i.next();
           h.printCardDetails();
       }
