java - 我如何主要使用其他代码？

Question

import java.util.Scanner;

class Character {
    public String name;
    public int hp;
    public int atk;
}//public class Character

class Wizard extends Character {
    public void main(){
        name = "Wizard";
        hp = 15;
        atk = 5;
    }
}//public class hero extends character

class Warrior extends Character {
    public void main(){
        name = "Warrior";
        hp = 20;
        atk = 3;
    }
}//public class hero extends character

class Monster extends Character {
    public void main() {
        name = "Monster";
        hp = 5;
        atk = 1;
    }
}//class Monster extends Character


public class Main{
        public static void main(String[] args) {

            Scanner sc = new Scanner(System.in);
            int hero;
            hero = sc.nextInt();

            if(hero==1)
            {
                human = new Warrior();

            } else if(hero==2){

                human = new Wizard();}
}

在这种情况下，java main找不到Warrior和Wizard以及怪物。我知道只能覆盖一次。但我希望主代码可以加载战士、巫师和怪物。我该如何修复它？有可能吗？感谢您的帮助。

你必须定义人类。在你的情况下可能是“角色”。更改后，您可以运行您的代码。

...
public class Main{
        public static void main(String[] args) {

            Scanner sc = new Scanner(System.in);
            int hero;
            hero = sc.nextInt();

            Character human; //add this line

            if(hero==1)
            {
                human = new Warrior();

            } else if(hero==2){

                human = new Wizard();}
}
