How do I make a deck of cards using ArrayLists?

For the deckOfCards class I am not allowed to use numbers, I have to use the getPossibleRanks() and getPossibleSuites() methods.

public class Card
{
   
    private String rank;//card rank: a number between 2 and 10, or Jack, Queen, King or Ace
    private char suit;//card suit: S,C,H,or D
    private static String[] Ranks={"2","3","4","5","6","7","8","9","10","Jack","Queen","King","Ace"};
    private static char[] Suites={'C','H','D','S'};
     
    /**
     * Constructor for objects of class Card
     */
    public Card()
    {
        rank="2";
        suit='H';
       
    }
   
    public Card(String rank, char suit)
    {
        this.rank=rank;
        this.suit=suit;
    }
     public String getRank()
    {
        return rank;
    }
   
    public char getSuit()
    {
        return suit;
    }
   
    public void setRank(String rank)
    {
        this.rank=rank;
    }
   
    public void setSuit(char suit)
    {
        this.suit=suit;
    }
    //Returns an array of possible card ranks
    public static String[] getPossibleRanks()
    {
        return Ranks;
    }
    //Returns an array of possible card suits
    public static char[] getPossibleSuits()
 {
        return Suites;
    }
   
    public String toString()
    {String suitName = "";
        switch (suit){
        case 'H':
         suitName = rank + " of Hearts";
            break;
         case 'S':
            suitName = rank + " of Spades";
             break;
              case 'D':
                suitName = rank + " of Diamonds";
                  break;
                  case 'C':
                   suitName = rank + " of Clubs";


    }
return suitName;
}
}

DeckOfCards class:

import java.util.Random;
import java.util.ArrayList;
public class DeckOfCards
{
    // instance variables - replace the example below with your own
    private ArrayList<Card> deck;
    Random getRandom = new Random();
    /**
     * Constructor for objects of class DeckOfCards
     */
    public DeckOfCards()
    {
        deck = new ArrayList<Card>();
        resetDeckOfCards();
    }
   
    public void resetDeckOfCards()
    {
       String[] ranks = Card.getPossibleRanks();
       char[] suites = Card.getPossibleSuits();
       
  for (int i = 0; i < getPossibleRanks().length ; i++)
       {
           for (int j = 0; j < getPossibleSuits().length; j++)
           {
              deck.add(new Card(ranks[j], suites));//
           }
       }    
    }
   
   
    public Card getCard()//remove random card of arraylist of cards and return value from method
    {
       if (deck.isEmpty())
            resetDeckOfCards();
       return deck.remove(getRandom.nextInt(deck.size()));              
    }
   
    public ArrayList<Card> getHand(int size)
    {
        ArrayList<Card> hand = new ArrayList<Card>();
        for (int i = 0; i < size; i++)
        {
            hand.add(this.getCard());
        }
        return hand;
    }
   
}
