适配器模式(Adapter)

定义:将一个类的接口转换为客户需要的另一个接口，适配器使原本由于接口不兼容而不能在一起工作的类可以一起工作

package com.eshore.zzy.design.pattern.adapter;

public interface Flyable {
 public void fly();
  }

package com.eshore.zzy.design.pattern.adapter;

public class OtherFrog extends Bird implements Swimable{
  public void swim(){
   System.out.println("swim........");
    }
  }

package com.eshore.zzy.design.pattern.adapter;

public class Bird implements Flyable{
 public void fly(){
  System.out.println("fly ,fly ,fly...");
   }
  }

package com.eshore.zzy.design.pattern.adapter;

public class Frog implements Flyable,Swimable{
 public void fly(){
  System.out.println("fly..........");
 }
 public void swim(){
  System.out.println("swimming.........");
   }
  }

 package com.eshore.zzy.design.pattern.adapter;

public class OtherFrog extends Bird implements Swimable{
  public void swim(){
   System.out.println("swim........");
    }
  }

适配器模式使用组合和继承的方式实现.
