如何使用预定义的牌组制作二十一点游戏 class

Question

所以在 class 中我们不得不做 ArrayBag class，我相信你们都知道。如果不是它在整个互联网上。不管怎样，我们的项目是把它变成黑杰克游戏。但是我不知道该怎么做。我想做一张牌 class 一副牌 class 然后是黑杰克 class。然而，我又一次不知道如何将它实现到 Array 包中 class。有人帮忙！我将添加我目前所拥有的代码。

数组包

package bag;

//I will will keep T because its the norm, but i really don't want to.
public class ArrayBag <T> implements BagInterface<T>{

private final T [] bag; // our generic array
private static final int DefualtItemCapacity = 52; // our default capacity of items...Make DEFAULT all caps because all the i's made it look ugly
private int numberOfItems ;


 public ArrayBag (int itemCapacity){
     numberOfItems = 0 ; // set numberOfItems to empty 0 
     @SuppressWarnings("unchecked") // java i know what im doing, #Suppressed !
     T[] tempBag = (T[]) new Object [itemCapacity];
     bag= tempBag;
 }// end constructor  

 public ArrayBag() {
     this(DefualtItemCapacity);
 } // if nothing, call DefualtItemCapacity, dont have to check for null if we overload the method 

 // thank you eclipse, for creating the methods from the interface :)
 @Override
 public int getCurrentSize() {
     // TODO Auto-generated method stub
     return numberOfItems;
 }// end current size

 @Override
 public boolean isFull() {
     // TODO Auto-generated method stub
     return numberOfItems==bag.length; // return numberOfItems as full 
 }// end full

 @Override
 public boolean isEmpty() {
     // TODO Auto-generated method stub
     return numberOfItems==0;// return numberOfItems as empty  
 }// end empty

 @Override
 public boolean add(T newItem) {
     boolean result = true ;
     if(isFull()){ // bag is full , return false
         result = false ;
     } else { // bag is not full add new item 
         bag[numberOfItems]= newItem ;
         numberOfItems++;
     }
     return result;
 }// end bool add

 @Override
 public T remove() {
     T temp = bag[numberOfItems-1]; // bag numberOfItems is now one less
     bag[numberOfItems-1]=null ; // then we have to set that spot to null 
             numberOfItems--; // then make sure numberOfItems is one less aswell

     return temp;
 }// end T remove

 @Override
 public boolean remove(T anItem) {
     boolean result = true ;
     for (int i = 0; i < numberOfItems; i++){
       if(bag[numberOfItems]== anItem ) {
             bag[numberOfItems] = null ;
/* items[numItems-1] = null;*/ // this might shift it left 
             numberOfItems--;
             result = true;
       }else {
             result = false ;   // item not found
       }

     }
     return result;
 }// end bool remove

 @Override
 public void clear() {
     while(!isEmpty()){ // while the bag is not empty we can remove stuff.
         remove();
     }

 }// end clear

 @Override
 public T grab() {
    int i;
    while (numberOfItems != 0){ // while numberOfItems is not empty
    i = (int)(Math.random( ) * numberOfItems) + 1; // i is a random value  
    return bag[i]; // return random item from bag
    }
    return null ; // is empty , return null
 } // end grab


 @Override
 public int getFrequencyOf(T anItem) { // count how many items are the same
     int count=0 ; // count how many are the same
     for (int i = 0; i < numberOfItems; i++){
         if(bag[i]==anItem){ // if current item = an item add to the count value
             count++;
         }
     }
     return count;
 }// end Frequency

 @Override
 public boolean contains(T anItem) {
    while(anItem != null){
     for (int i = 0; i < numberOfItems; i++){
         if (anItem.equals(bag[i])){ //bag contains the specified item, use .equals because java is dumb and == gives an error.
             return true;
             }
     }
    }return false; // bag doesnt contain item

 }// end contains

 @Override
 public T[] toArray() { // creates and returns an array containing all of the items
     T[] result = (T[]) new Object [numberOfItems]; 
     for(int i =0; i < numberOfItems; i++){
         result[i]=bag[i];
     }
     return result;
 } // end toArray
} // end class

卡片Class

package bag;

public class Card {
private String cardSuit ; 
private int card ; 

 Card(String suit, int card ){
    this.cardSuit = cardSuit ; 
    this.card = card ;
}
 public String toString(){ // Mr.Englend, i overloaded the toString :'(
     String CardNumber = null; 

         switch (this.card){ 
         case 1: 
             CardNumber = "Ace" ; 
             break;
         case 2: 
             CardNumber = "Two" ; 
             break;
         case 3: 
             CardNumber = "Three" ; 
             break; 
         case 4: 
             CardNumber = "Four" ; 
             break; 
         case 5: 
             CardNumber = "Five" ; 
             break; 
         case 6: 
             CardNumber = "Six" ; 
             break; 
         case 7: 
             CardNumber = "Seven" ;  
             break; 
         case 8: 
             CardNumber = "Eight" ;  
             break; 
         case 9: 
             CardNumber = "Nine" ; 
             break; 
         case 10 :
             CardNumber = "Ten" ; 
             break ; 
         case 11: 
             CardNumber = "Jack" ;
         case 12: 
             CardNumber = "Queen" ;
        case 13:
            CardNumber = "King" ;
            break; 
        case 14:
            CardNumber = "Ace" ;
            break; 
        default: 
            CardNumber = "ERROR" ;
            break; 
            }

            return CardNumber + "Of " +cardSuit.toString() ; 
 }
}

二十一点Class

   package bag;

import java.util.Scanner;

public class BlackJack {
private static  ArrayBag Deck = new ArrayBag();
private Card[] mycard ; 
//private static  Card Card = new Card();


 public static void main(String[] args) {
      boolean play = true ;
      boolean winner = false ; // bool win
      int money = 100 ;  // amount of money
      int bet = 0 ;  // amount user bets
      Scanner input = new Scanner(System.in);
      Deck.add(3);
      System.out.println(Deck.isEmpty());
      System.out.println(Deck.contains(3));
      System.out.println(Deck.toArray());

      }// end main

 void shuffle(){
     for(int i = 1; i <= 52 ; i++){
         System.out.println(Deck.add(i));
     }

 }

      void drawCard(){
          while(!Deck.isEmpty()){ 

          } // end while not empty

      } // draw card

    }// end class
