Question

JAVA:

Playing cards are used in many computer games, including versions of such classics as solitaire, hearts, and poker. Design a Card class that contains a character data field to hold a suit (s for spades, h for hearts, d for diamonds, or c for clubs) and an integer data field for a value from 1 to 13. Include get and set methods for each field. Save the class as Card.java.

Then:

Write an application that randomly selects two playing cards and displays their values. Simply assign a suit to each of the cards, but generate a random number for each card’s value. Copy the following statements to generate a random number between 1 and 13 and assign it to a variable: final int CARDS_IN_SUIT = 13; myValue = ((int)(Math.random() * 100) % CARDS_IN_SUIT + 1);

. Save the application as PickTwoCards.java.

Explanation / Answer

// Card.java
public class Card
{
   private char suit;
   private int number;

   // getter for card number
   public int getNumber()
   {
       return number;
   }
  
   // getter for card suit
   public char getSuit()
   {
       return suit;
   }
  
   // setter for card number
   public void setNumber(int number)
   {
       this.number = number;
   }
  
   // setter for card suit
   public void setSuit(char suit)
   {
       this.suit = suit;
   }
}

// PickTwoCards.java

public class PickTwoCards
{
  
   public static void main(String[] args)
   {
       final int CARDS_IN_SUIT = 13;

       int value1 = ((int)(Math.random() * 100) % CARDS_IN_SUIT + 1);
       int value2 = ((int)(Math.random() * 100) % CARDS_IN_SUIT + 1);
      
       Card c1 = new Card();
       c1.setNumber(value1);
       c1.setSuit('s');

       Card c2 = new Card();
       c2.setNumber(value2);
       c2.setSuit('d');

       System.out.println("First card => Suit: "+ c1.getSuit() + " Number: " + c1.getNumber());
       System.out.println("Second card => Suit: "+ c2.getSuit() + " Number: " + c2.getNumber());
   }
  

}

/*
output:

First card => Suit: s Number: 1
Second card => Suit: d Number: 8
