Java基础-接口看下图实现如下接口和类，并完成Adventure中的主方法

package hanqi;

public interface CanSwim {

    void swim();
}

package hanqi;

public interface CanFly {
    
    public void fly();

}

package hanqi;

public abstract class ActionCharacter {

      abstract void fight(String emp);
        
      abstract void speak(String s);
    
}

package hanqi;


public class Hero  extends ActionCharacter implements CanFly, CanSwim{

     String name;
        Hero(String name)
        {
            this.name=name;
        }

        
        public void swim() {
            System.out.println(this.name+",游泳");

        }


        public void fly() {
            System.out.println(this.name+",飞");

        }


        void fight(String emp) {
            System.out.println(this.name+","+emp);

        }


        void speak(String s) {
            System.out.println(this.name+","+s);

    

        }
}

package hanqi;

public class Adventure {

    public static void main(String[] args) {
        // TODO 自动生成的方法存根
        
        Hero hb = new Hero("A");
        hb.swim();
        hb.fight("B");
        hb.fly();
        
        CanFly cf = hb;
        hb.fly();
        
        CanSwim cs = hb;
        hb.swim();
        
        
        ActionCharacter ac = hb;
        ac.speak("C");
        ac.fight("D");
        
        

    }

}
