这是玩我制作的猜谜游戏的代码，但问题是我作为java初学者不擅长的几个问题需要一些指导。沿着代码有一些错误，我用侧面的箭头突出显示。

    import java.util.*;

public class GuessingGame
{


    private static Player house;
    private static Player player;

    private static int wins;
    private static int loses;
    private String name;
    int card1,card2;
    private int value;



    public void Player(String name){

        this.name=name;
        card1 = (Integer) null;
        card2 = (Integer) null;
    }



public void Card(int value){

     this.value = value;
    }





public int getValue(){
            return value;
        }



public void acceptDeal(Card card1, Card card2){
        Random r = new Random();
        int value = r.nextInt(13) + 1;
        card1 = new Card(value);            <<<<<<<<======= Error 1
        value = r.nextInt(13) + 1;
        card2 = new Card(value);            <<<<<<<<======= Error 2
    }



public static void init()
{

    house = new Player("House");                 <<<<<<<<======= Error 3
    player = new Player("Player");               <<<<<<<<======= Error 4
    wins = 0;
    loses = 0;

}

首先欢迎来到 StackOverflow。很高兴看到您找到并使用了 homework 标签。请记住，为了让人们能够帮助您，您需要提供更多信息。错误是什么意思，运行代码时会发生什么等

关于你得到的错误，看起来你还没有真正定义类Card，Player你的代码中有两个方法GuessingGame.Card()和GuessingGame.Player()你的GuessingGame类。将它们更改为内部（或外部）类，应该没问题；）

也许您需要在顶部导入其他类？

问题似乎只存在于您自己的课程中，程序输出对错误有什么看法？

public void Player(String name)……和 public void Card(int value)……

应该上课吧？将它们声明为另一个文件中的类并将它们包含到主文件中。

在您之前的问题 card1中card2，类型为Card. 没错，现在你已经改变了这一点，现在它是错误的。

你似乎已经把你的代码打包了。您已经组合了 Player、Card 和 Game 类。我手边没有 Java 编译器，但您要做的是分解这三个模型。

错误 1-6 是在类甚至不存在时尝试实例化新对象的结果。错误 7-8 是由于尝试调用同一方法的结果。

import java.util.*;

class Player {
    int card1, card2;
    private String name;

    public void Player(String name){
        this.name=name;
        card1 = (Integer) null;
        card2 = (Integer) null;
    }

    public void acceptDeal(Card card1, Card card2){
        Random r = new Random();
        int value = r.nextInt(13) + 1;
        card1 = new Card(value);            <<<<<<<<======= Error 1
        value = r.nextInt(13) + 1;
        card2 = new Card(value);            <<<<<<<<======= Error 2
    }
}


class Card {
    private int value;

    public void Card(int value){
        this.value = value;
    }

    public int getValue(){
        return value;
    }
}
