USING JAVA MODIFY THE CODE FOLLOWING THESE STEPS:
Part 1: Build the Deck
Add code to the getDeck() method so it returns a standard deck of 52 cards.
To do that:
Create one array of strings for the four suits (Spades, Hearts, Clubs, Diamonds) and a second array of strings for the 13 ranks for each suit. You can hard code the values using the curly braces method.
Then create a nested loop to loop through the suits array and inside loop through the ranks array. All while concatenating the current suit with current rand and putting it into a String array. This is the array that you will return. Note that it is NOT a 2D array. We are just using nested loops to help build a single array not a 2D Array.
HINTS: You will need a variable counter that you use to assign each value in the deck array. After each iteration you would need to increase it (counter++) so that you can assign the next value.
Part 2: Display the Deck
Add code to the displayCards() method so it prints all cards in the array that's passed to it.
Use a simple for loop to print out the contents of the array, separate each card with a pipe character ( | ).
Once this method is written you should be able to test your code and see that the deck of cards prints out. If it doesn't match the first part of the output from the above image then you may have to not only check your code for this part but revisit part 1 to make sure that is done correctly.
Part 3: Shuffle the Cards
Add code to the shuffleDeck() method that shuffles the deck of cards.
You will want to loop through the array and swap each card with a card at random
To do this get a random number between 0 - the size of the array that you then swap the values.
to do a swap remember that you need to save the old value of one of the elements to a temporary variable to then perform the saw and assign the temp variable back to the array element
Part 4: Deal the Cards
Add code to the dealCards() method that creates a hand of cards by dealing the specified number of cards from the cards array. Notes this value is sent to the method as an argument.
Take the first cards in the deck up until the sent count amount
You will need to return a String array of the hand dealt.
Notice the hand array is created for you based on the count variable size
You can use a loop to assign values but you can also use the Array class to help you copy it.
Part 5: Check your Program
Lastly you should run the program and the final output should be similar to the image provided above. The only difference is that the SHUFFLED DECK part should be different each time. Also make sure that the HAND OF 2 CARDS matches the first two cards from SHUFFLED DECK and is not blank.
THE CODE TO MODIFY IS BELOW:
public class CardDeckApp { public static void main(String[] args) { System.out.println("DECK"); String[] deck = getDeck(); displayCards(deck); System.out.println("SHUFFLED DECK"); shuffleDeck(deck); displayCards(deck); int count = 2; System.out.println("HAND OF " + count + " CARDS"); String[] hand = dealCards(deck, count); displayCards(hand); } private static String[] getDeck() { String[] deck = new String[52]; // add code that creates deck here return deck; } private static void displayCards(String[] cards) { // add code that displays cards here } private static void shuffleDeck(String[] deck) { int randomIndex = (int) (Math.random() * deck.length-1); // add code that shuffles the deck here } private static String[] dealCards(String[] deck, int count) { String[] hand = new String[count]; return hand; } }
