JAVA接口的简单实现

感觉越来越强烈，

我的心在跳~~~，我的宝剑在嘟~~

Flyer.java

package cc.openhome;

public interface Flyer{
    public abstract void fly();
}

Swimmer.java

package cc.openhome;

public interface Swimmer{
  public abstract void swim();
}

Fish.java

package cc.openhome;

public abstract class Fish implements Swimmer {
  protected String name;
  public Fish(String name){
    this.name = name;
  }
  public String getName() {
    return name;
  }

  @Override
  public abstract void swim();
}

FlyingFish.java

package cc.openhome;

public class FlyingFish extends Fish implements Flyer {
    public FlyingFish(String name){
        super(name);
    }

    @Override
    public void swim(){
        System.out.println("FlyingFish swim");
    }

    @Override
    public void fly(){
        System.out.println("FlyingFish fly");
    }
}

SeaPlane.java

package cc.openhome;

public class Seaplane implements Swimmer, Flyer {
  private String name;

  public Seaplane(String name){
    this.name = name;
  }

  @Override
  public void fly() {
    System.out.printf("Seaplane %s is fly", name);
  }

  @Override
  public void swim(){
    System.out.printf("Seaplane %s is swim", name);
  }
}

Ocean.java

package cc.openhome;

public class Ocean {
  public static void main(String[] args){
    doSwim(new Seaplane("AirFoce Zero"));
    doSwim(new FlyingFish("Flying Ping"));
  }
    static void doSwim(Swimmer swimmer){
        swimmer.swim();
    }
}
