Question

A Driver class that does the following: a. Creates a new deck of cards (unshuffled). b. Displays a menu of choices as follows: Enter the number of one of the following choices. 1. Shuffle the deck. 2. Print the cards remaining in the deck. 3. Remove all the cards of a specified rank. 4. Quit. c. Use a Scanner object to read the input. d. Use a switch statement to execute the user's choice. i. Use a Scanner object (if necessary) to read the required input. e. Use a loop to repeat until the user quits.

This is what I have so far.

I'm getting an error on the ...

case 3: System.out.println("Enter the rank of the card you want removed");

cards.remove();

System.out.println();

break;

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

package PlayingCards;

import java.util.Scanner;

public class Driver

{

public static void main(String[] args)

{

Scanner sc = new Scanner(System.in);

boolean done = false;

int menuInput;

DeckOfCards cards = new DeckOfCards();

do

{

System.out.println("Enter the number of one of the choices below:");

System.out.println("1: Shuffle The Deck.");

System.out.println("2: Print The Cards Remaining In The Deck.");

System.out.println("3: Remove All Of The Cards Of A Specific Rank. ");

System.out.println("4: Quit");

menuInput = sc.nextInt();

sc.nextLine();

switch (menuInput)

{

case 1: System.out.println("Shuffled the Deck");

cards.shuffle();

break;

case 2: System.out.println("Printing all cards left in the deck");

cards.print();

break;

case 3: System.out.println("Enter the rank of the card you want removed");

cards.remove();

System.out.println();

break;

case 4: done = true;

System.out.println("Goodbye.");

break;

default: System.out.println("Incorrect entry, please try again.");

}

}

while (!done);

}

}

Hi. I have answered previous part of this question. There was a small error in your code, you didn’t read the rank of cards to remove and was just calling the remove method without rank value. Fixed it. Here is the completed code for this problem. Comments are included, go through it, learn how things work and let me know if you have any doubts or if you need anything to change. If you are satisfied with the solution, please rate the answer. Thanks

// Driver.java

package PlayingCards;

import java.util.Scanner;

public class Driver

{

    public static void main(String[] args)

    {

         Scanner sc = new Scanner(System.in);

         boolean done = false;

         int menuInput, rank;

         DeckOfCards cards = new DeckOfCards();

         do

         {

             System.out.println("Enter the number of one of the choices below:");

             System.out.println("1: Shuffle The Deck.");

             System.out.println("2: Print The Cards Remaining In The Deck.");

             System.out

                      .println("3: Remove All Of The Cards Of A Specific Rank. ");

             System.out.println("4: Quit");

             menuInput = sc.nextInt();

             sc.nextLine();

             switch (menuInput)

             {

             case 1:

                 System.out.println("Shuffled the Deck");

                 cards.shuffle();

                 break;

             case 2:

                 System.out.println("Printing all cards left in the deck");

                 cards.print();

                 break;

             case 3:

                 System.out

                          .print("Enter the rank of the card you want removed: ");

                 // reading rank value

                 rank = sc.nextInt();

                 // removing all cards with the above rank, assuming rank is

                 // valid. this should be a value between 1 and 13

                 cards.remove(rank);

                 System.out.println();

                 break;

             case 4:

                 done = true;

                 System.out.println("Goodbye.");

                 break;

             default:

                 System.out.println("Incorrect entry, please try again.");

             }

         }

         while (!done);

    }
