Question

类和源文件称为textadv1

错误消息是“无法访问类型为textadv1的封闭实例。必须使用类型为textadv1的封闭实例来限定分配，例如x.new（A），其中x是textadv1的实例”

代码“导致”错误出现在这里：room startRoom = new room（）; {

import java.util.*;
/**

/**

public class textadv1 {

    /**

        }

Answer 1

您正在尝试从non-static块访问static类。

请提及您的房间教室为静态教室，这样就可以了

public static class room{

Answer 2

这主要是由于您从静态上下文中进行了非静态引用所致。

您的main方法不是静态的，而您的rooms方法是静态的。你可以
1.使rooms类为静态
2.将您的rooms类放在您的textadv1类之外（在这种情况下，删除公共访问说明符）

Answer 3

您正在尝试从静态块访问非静态类。 Main是静态的，因此您的房间等级也应该是静态的

Answer 4

在访问（非静态）内部类时，您需要具有一个封装外部类的实例。在这种情况下，在线83和89上没有该封闭实例。因此，您应该首先创建textadv1的实例，然后使用该实例创建room对象，如下所示：在第83行上添加textadv1 txtadv = new textadv1();，然后使用 room startRoom = txtadv.new room();代替room startRoom = new room();

，并且也使用room room0 = txtadv.new room();代替room room0 = new room();
