Question

从我的理解，这是我试图做的，我正在创建一个界面来概述角色是什么，

我正在创建一个类来定义角色将使用的每个方法在同一个类中，我根据自己的喜好多次创建该角色的新对象。

所以，如果我想制作10个字符，我只是从同一个班级做到这一切？

目前我试图通过赋予它一个属性来创建一个角色。

然后我想System.out.prinln但是当我编译时我得到了

javac Hero.java
Hero.java:3: error: interface expected here
public class Hero implements Character {
                             ^
1 error

我改变了Character to Player，这就是我得到的，

javac Hero.java Hero.java:3: error: cannot find symbol public class Hero implements Player {                              ^   symbol: class Player 1 error

2个文件Character Interface和Hero Class 公共界面角色{

        // define methods that must be defined across all character types
        int getLevel();
        String getPrimaryAttribute();
        String getAttackType();
        String getAbility1();
        String getAbility2();

Answer 1

Java已经定义了一个Character类（在java.lang包中）。

Character类在对象中包装基本类型char的值。 Character类型的对象包含一个类型为char的字段。

编辑 - 默认情况下导入此包java.lang，因此接口名称与此包中定义的Character类冲突。因此，这个问题。最好避免使用完全相同的名称。
