Question

我正在使用java进行视频扑克任务。我们给出了我们应该在我们的程序中使用的类模板。我对Card c所代表的内容感到困惑。与方法addCard(Card c)一样，这是否意味着它将在当前正在使用的Card对象上执行？以下是我目前一直在处理的类文件。它们还远没有完成。

玩家等级：

import java.util.ArrayList;
public class Player {


private ArrayList<Card> hand; // the player's cards
// you will likely need more instance variables

public Player(){        
    ArrayList<Card> hand = new ArrayList;
}

public void addCard(Card c){
    // add the card c to the player's hand
}

public void removeCard(Card c){
    // remove the card c from the player's hand
}

// you will likely need more methods here
}

甲板课程：

import java.util.Random
public class Deck {

private Card[] theDeck; 
private int top; 
// add more instance variables if needed

public Deck(){
    top = 0
    Card[] theDeck = new Card[52];
    for(int s = 1; s <= 4; s++)
    {
    for (int v = 1; v <= 13; v++)
    {
        for (int i = 0; i < theDeck.length; i++)
            theDeck[i] = new Card(s,v);
}

public void shuffle()
{
    // shuffle the deck here
    Random generator = new Random();
    int i;
    int j;
    int temp = i;
    int i = generator.nextInt(51) + 1;
    int j = generator.nextInt(51) + 1;
    for(int k = 1; k <100; k++)
    {
        theDeck[i] = theDeck[j];
        theDeck[j] = temp;
    }
    top = 0;
}

public Card deal(){
    // deal the top card in the deck
    if (top < 40)
    {   
        theDeck.shuffle;
    }
    return theDeck[top];
    top++;
}   //this method should add cards to array hand? no addCard will do that.





// add more methods here if needed
//DB getter methods here?

}

卡类：

public class Card implements Comparable<Card>{

private int suit; 
private int value; 

public Card(int s, int v){ //constructor of an object Card
    s = suit;
    v = value;
    //make a card with suit s and value v
}

public int compareTo(Card c){
    // use this method to compare cards so they 
    // may be easily sorted

}

public String toString() //to tell the user what card/s they have
{
    myCard.getSuit();
    myCard.getValue();
    if(s == 1)
    {
        if(v == 11)
        {
            return "Jack of Clubs";
        }
        if(v == 12)
        {
            return "Queen of Clubs";
        }
        if(v == 13)
        {
            return "King of Clubs";
        }
        if(v == 1)
        {
            return "Ace of Clubs";
        }
        else{
            return v + " of Clubs";
        }   
    }
    if(s == 2)
    {
        return v + "Diamonds";
    }
    if(s == 3)
    }
        return v + "Hearts";
    }
    if(s == 4)
    }
        return v + "Spades";
    }


//DB method to set 1, 2, 3, and 4 to card suits


//now here create string representation for the Card    
    // use this method to easily print a Card object

public int getSuit()
{
    return s;
}
public int getValue()
{
    return v;
}   

//DB right now have cards in theDeck like Card(2, 10), need Card(d, 10)
//need to convert that to a String d10 
}
// add some more methods here if needed

}

Answer 1

在public void addCard(Card c)中，c是parameter。

这意味着在函数addCard的主体内，您可以引用通过名称c传递给函数的值。您调用函数addCard并使用某个值（例如theDeck[0]），该值将在addCard()中使用。
