Question
Program 1d: FiveCards in Java.
Hello Chegg,
I have been tyring to complete this lab for quite some time now but have seemed to get stuck and was wodnering if I could get assistants to finsh the class. I also attached (the bottom) my own code, and was wondering if we could use it to finsh the rest of the lab.
Thank You so much! ( I always rate positively ) ..... :)
Objectives
Work with arrays that correspond to a standard poker card deck.
Use Random number generator.
Write various methods to convert index to a card suit and rank.
Assignment
Write an application called FiveCards.java that randomly selects five unique numbers from 0 to 51 which will represent individual cards in a standard 52-card four-suited poker deck of cards.
Methods
public static void main (String[] args)
Call initHand to initialize the one-dimensional "hand" of cards with 52 card deck, 5 card hand and seed 1111.
Call showHand to print the string representation of the number in the hand of cards array.
Call sameSuit to print any cards in the hand that have the same suit.
public static int[] initHand(int deckSize, int handSize, long randomGeneratorSeed)
This method returns a one-dimensional array of handSize integer values, each between 0 and deckSize.
For this program, an example of a hand array is:
This method should create a Random object seeded with randomGeneratorSeed once BEFORE any loop is entered.
Random rand = new Random(randomGeneratorSeed)
After this, rand.nextInt(deckSize) inside the loop will generate the next successive value.
Unique cards: you must handle the case where number is randomly generated that has already been used in the hand array. For example, `initHand(52, 5, 31) generates, in order, 20, 12, 20, …
public static void showHand(int[] hand)
This method displays each card on one line in the order it was dealt (placed into the hand array) by calling getCardValue for each card in the array.
public static void sameSuit(int[] hand)
This method calls getCardValue to display any two or more cards having the same suit. This will be as few as two cards or as many as five. This method will require some strategy. It should be able to detect any of the following scenarios.
Two or more cards of the same suit. A hand may have more multiples of more than one suit, for example, two Hearts cards and two Clubs.
A "full house" would consist of two cards of one suit and three cards of another suit.
A "flush" would be five cards all of the same suit.
Cards should be printed in ascending rank order (sort the hand array from smallest to largest).
public static String getIdentificationString()
This method returns a string containing "Program 1, Student Name"
public static String getCardValue(int cardNumber)
This method rerturns the value of a card having the form " of ". For example, "Ace of Hearts", "Two of Diamonds", "Queen of Spades."
The rank is determined by calling getRank and suit is determined by calling getSuit.
public static String getSuit(int cardNumber)
Returns a string containing the suit of the card where
public static String getRank(int cardNumber)
Returns a string containing the rank of the card where
Notes
import java.util.Arrays to use Arrays.sort(myHandArray) if desired
import java.util.Random for random numbers
Testing
Your program should run with a variety of inputs. Test as many as you can to find unique outputs! Focus on changing the seed value. Here are some examples: 1, 8, 81, 111, 1111, 11111, 31.

cardType [i] = rand.nextInt(deckSize);
}
return cardType;
}
public static void showHand(int[] hand) {
}
public static String getCardValue(int cardNumber) {
String toYes = "Yo";

Explanation / Answer
I have completed the solution and it is working perfectely fine. There were some mistakes in your code but I have corrected them. Please give me an upvote.
