如何在【】处补充代码，完成抽象类的定义以及相关功能？

Question

    【】Actor{
    int health=100;
    public abstract  void ShowStatus();
        public void attack(){
        }
        public void setHealth (int health ){
            this.health=health;
        }
}
class Hero extends Actor {
              【】
    }
public class Main{
    public static void main(String []args){
                 【】
    }
}

在【】处补充代码，完成抽象类的定义以及相关功能。输出：health:100

Answer 1

参考如下：

abstract class Actor {
    int health = 100;

    public abstract void ShowStatus();

    public void attack() {
    }

    public void setHealth(int health) {
        this.health = health;
    }
}

class Hero extends Actor {

    @Override
    public void ShowStatus() {
        System.out.println("health:" + health);
    }
}

public class Main {
    public static void main(String[] args) {
        Actor heroActor = new Hero();
        heroActor.ShowStatus();
    }
}
