Question

目前，我正在完成这项任务，目前我已经完成了大部分工作。

public String getRankAsString() {
String[] ranks = "2", "3", "4", "5", "6", 
"7", "8", "9", "10", "J", "Q", "K", "A" 
return ranks[rank];
}

和西装

public String getSuitAsString() {
String[] suits = { "Clubs", "Diamonds", 
"Hearts", "Spades" };
    return suits[suit];
}

我应该在实验室软件包中创建2个类，一个称为LabApp（将在其中进行测试），而DiscardPile是Stack的子类，将包含方法“ discardTopCard”，称为removeTopCards的方法，该方法接受一个引用称为Card的Card对象。此方法将允许用户请求从丢弃堆中取出所有包括CardCard的卡片，并以数组形式返回，因此该方法的返回类型为Card []。这就是我的removeTopCard atm。

public Card[] removeTopCard(Card otherCard) throws StackEmptyException {
        Card[] theCard = new Card[size()];
        int i = 0;
        boolean check = false;

        if(isEmpty()){ //in the case that there's nothing there
          throw new StackEmptyException("Stack is Empty");
        }
        while(!isEmpty()){ //If it's not empty, pop the top card (unlimited loop that'll need to be broken by a break;)

          Card top = (Card) pop(); //Casts Card to pop, which should remove it
          theCard[i] = top; //removed and returned in an array
          i++; 
          if(top.equals(otherCard)){ //checks if the card's rank and suit are the same and stops the loop if true
            check = true;
            break; //it ends the loop if they're equivalent, all of those cards were set to top
          }
        }
        if(!check){ //if it can't find anything
          throw new StackEmptyException("Card not found");
        }
        Card[] topCards = new Card[i];

        for(int j = 0;j < i; j++){

          topCards[j] = theCard[j]; //set the discarded value array to theCard
        }
        return topCards; //should return the popped numbers
      }

我认为，这可能很好。

在LabApp（一种测试方法）中，我目前拥有工作正常的throwsPile.push方法

        discardPile.push(new Card(41));

        for(int i = 0; i < discardPile.getSize(); i++) {
            Card var = discardPile.pop(); //pops the cards that are above
                System.out.println(var.getRankAsString() + " of " + var.getSuitAsString());
        }

        }
        catch (StackEmptyException SEE) {
            System.out.println("StackEmptyException: " + SEE.getMessage());
        }
        catch (StackFullException SFE) {
            System.out.println("StackFullException: " + SFE.getMessage());
       }
}
}

它正在打印所需的输出，没问题

我还应该编写调用removeTopCards方法，并通过将引用传递给整数值为20的卡来测试该方法。

我知道我是这样写的

discardPile.removeTopCard(new Card(20));

但是我不知道如何通过for循环打印它。

任何帮助将不胜感激。

如何将方法（removeTopClass）从另一个类打印到循环中？
