Java Program**
Write a program that reads in a hand of cards and stores it in an array of sets, one set for each suit.
Each card is represented using a pair of characters.
The first character represents the rank of the card: the digits 2 through 9 stand for themselves, and the letters T, J, Q, K, A stand for ten, jack, queen, king, and ace, respectively.
The second character denotes the suit: C, D, H, or S. Check for invalid cards and duplicate cards.
Your program must use function(s) and must be Object Oriented. Your function(s) must use arguments.
Explanation / Answer
//Main Class
import java.util.*;
class Main1{
public static void main(String[] args){
Scanner s = new Scanner(System.in);
Set<Cards> cardRead = new HashSet<>();
while(true){
System.out.println("Select a card to add in deck(Rank,Suit).If finished enter 0.");
String read = s.nextLine();
if(read.compareTo("0")==0)
break;
Cards newCard = new Cards(read);
if(cardRead.contains(newCard))
System.out.println("Dupilcate Card");
else cardRead.add(newCard);
}
}
}
//Cards Class
import java.util.*;
public class Cards {
private char rank;
private char suit;
public void cardCheck(char a, char b){
if(a!= 'A'&& a!='2' && a!='3' && a!='4' && a!='5' && a!='6' && a!='7' && a!='8' && a!='9' && a!='T' && a!='J'&& a!='Q' && a!='K' )
{
System.out.println("Invalid Card");
}
else if(b!='C'&& b!='D' && b!='H' && b!='S')
{
System.out.println("Invalid Card");
}
else
{
rank = a;
suit = b;
}
}
public Cards(String input){
cardCheck(input.charAt(0),input.charAt(1));
}
public Cards(){
}
public char getRank(){
return rank;
}
public char getSuit(){
return suit;
}
@Override
public boolean equals(Object o){
Cards card = (Cards) o;
if(hashCode()==card.hashCode()){
return true;
}
else
return false;
}
@Override
public int hashCode(){
return Objects.hash(rank,suit);
}
}
// I hope it is understandable and met your expectations. You can use try catch statements for more stability. I didnt //have enough time to add them but the program works just fine if the user inputs in the given format. All the best !!
