What is the significance of blackjack game java?

I've created a relatively simple Blackjack game in java. The reason why I decided to do this specific project was to improve my object oriented programming in java.

I will post my code so feel free to come with criticism etc. I am reading my first course in Java, with that in mind.

Player class

import java.util.ArrayList;
public class Player {
private String nickName;
private int playerNum Cards;
ArrayList playerHand;
public Player (String name){
    this.nickName = name;
    playerHand = new ArrayList();
}
public String getNickName() {
    return nickName;
}
public void addCard(Card aCard){
    playerHand.add(aCard);
    this.platiNum Cards;
}
public int getHandSum(){
    int totalSum = 0;
    for(Card countSum: playerHand){
        totalSum = totalSum + countSum.getFace();
    }
    return totalSum;
}
public void getPlayerHand(boolean hideCard) {
    System.out.println(this.nickName + "s current hand.");
    for ( int c = 0; c < playerNumOfCards>        if(c == 0 && !hideCard){
            System.out.println("[Hidden card]");
        } else {
            System.out.println(playerHand.get(c).toString());
        }
    }
}
}
Card class
public class Card {
private Face face; //Face of card, i.e "King" & "Queen"
private Suit suit; //Suit of card, i.e "Hearts" & "diamonds"
int total = 0;
public Card (Face cardFace, Suit cardSuit){ //Constructor which initialises card's face and suit
    this.face = cardFace;
    this.suit = cardSuit;
}
public int getFace(){
     return face.getFaceValue();
}
public String getSuit(){
    return suit.PrintSuitText();
}
public String toString(){ //return String representation of Card
    return face + " of " + suit;
}
}
Suit enum
public enum Suit {
HEARTS(" Hearts"),
SPADES(" Spades"),
DIAMONDS(" Diamonds"),
CLUBS(" Clubs");
private final String suitText;
private Suit(String suitText){
    this.suitText = suitText;
}
public String PrintSuitText(){
    return suitText;
}
}
Face enum
public enum Face {
ACE(1), DEUCE (2), THREE (3),
FOUR(4), FIVE(5), SIX(6),
SEVEN(7), EIGHT(8), NINE(9),
TEN(10), JACK(10), QUEEN(10),
KING(10);

private final int faceValue;

private Face(int faceValue){

    this.faceValue = faceValue;

}

public int getFaceValue(){

    return faceValue;

}

}

DeckOfCard class

import java.util.Random;

public class DeckOfCards {

private Card[] deck;

private static final Random random = new Random();

private int currentCard; //index of next Card to be deal (0-51)

private static int NUMBER_OF_CARDS = 52; //Constant number of cards

public DeckOfCards(){

    Face [] faces = {Face.ACE, Face.DEUCE, Face.THREE, Face.FOUR, Face.FIVE, Face.SIX,

                     Face.SEVEN, Phase.EIGHT, Face.NINE, Face.TEN, Face.JACK, Face.QUEEN,

                     Face.KING};

    Suit[] suits = {Suit.HEARTS, Suit.SPADES, Suit.DIAMONDS, Suit.CLUBS};

    deck = new Card [NUMBER_OF_CARDS]; // create array with Cards (52)

    currentCard = 0;

    //Populate deck with Cards

    for(int count = 0; count < deck>

        deck [count] = new Card(faces [count ], suits [count / 13]);

}

public void shuffleDeck(){

    currentCard = 0;

    for (int first = 0; first < deck>

        int second = random.nextInt(NUMBER_OF_CARDS); //Select a random card from number 0-51 (Number_of_cards)

        //Loops through all the cards and swaps it with the "Second" card which is a randomly chosen card from the same list.

        Card temp = deck[first];

        deck [first] = deck [second];

        deck [second] = temp;

    }

}

public void getCardDeck(){

    int start = 1;

    for(Card k : deck) {

        System.out.println("" + start + "/52 " + k);

        start++;

    }

}

public Card dealNextCard(){

    //Get the top card

    Card topCard = this.deck[0];

    //shift all the subsequent cards to the left by one index

    for(int currentCard = 1; currentCard < NUMBER>

        this.deck[currentCard-1] = this.deck[currentCard];

    }

    this.deck[NUMBER_OF_CARDS-1] = null;

    //decrement the number of cards in our deck

    this.NUMBER_OF_CARDS--;

    return topCard;

}

}
