Java早期发行版中的UNO游戏

作为本周任务的一部分(计算机编程I),我应该研究我们在整个课堂上都在从事的UNO游戏。游戏只能在两台计算机之间进行,因此除了偶尔的输入才能使游戏继续进行之外,没有键盘输入(有点闷吗?)。这周我们应该为游戏的每个部分进行一些分类(例如CARD类和HAND类)。我能够做到这一点,但是我的任务的第二部分是拥有一个驱动程序: 的UNO卡,将卡分发给两个或更多玩家,并显示每个卡的内容 玩家的手。”-我被卡住了。我尝试了多种印刷方法,这些方法以我极其有限的技能知道,但是我什么也没想出来。有什么想法吗?

这是代码:

public class CARD
{
    public String color;
    public int value;
    private Random random;
    private String face;

    public CARD(int v,String c)
    {
        value = v;
        color = c; 
    }

public CARD()
{
    random = new Random();
    value = random.nextInt(28); // 108 cards in a deck and it Can be reduced to 27 which ignores colors
    // Assigns value
    if (value >= 14) // Some cards show up more often (numbers)
        value -= 14;
    // Assigns color
    random = new Random();
    switch(random.nextInt(4) ) //learned about switches here: https://www.youtube.com/watch?v=RVRPmeccFT0
    {
        case 0: color = "Red"; 
            break;
        case 1: color = "Green"; 
            break;
        case 2: color = "Blue"; 
            break;
        case 3: color = "Yellow"; 
            break;
    }
    // If the card is wild 
    if (value >= 13)
        color = "none";
    }
}

根据您提供的代码,我建议使用for循环制作卡片:

public class DriverProgram {
    static final int players = 2,numberOfCards = 7;
    public static void main (String[] args){
         java.util.ArrayList<CARD> c = new java.util.ArrayList<CARD>();
         for(int i=0; i<numberOfCards; i++){
             c.add(new CARD()); // The previous example used a fixed size array
         } // Arrays.fill() would make all the cards identical
         System.out.println(c); 
         // Note: ArrayLists print themselves nicely with their toString method.
         // If you'd like,you could do String.replace("[","").replace... to remove
         // certain characters.
    }
}

How do I print my Java object without getting "SomeType@2f92e0f4"?
