Java设计模式之适配器模式

适配器模式：

1，类适配器模式

源角色(Adaptee):

package com.classadpter;
public class Adaptee {
   public void code(){
       System.out.println("能写代码");
   }
}

目标抽象角色(Target):

package com.classadpter;
public interface Target {
public void code();
public void pm();
}

适配器角色(Adapter)

package com.classadpter;
//Adpter：就是继承Target,继承Adaptee
public class Adapter extends Adaptee implements Target {
//这里这个IT民工即能写代码，也想能做产品,话说好多coder都喜欢这么yy来着
   @Override
   public void pm() {
       // TODO Auto-generated method stub
       System.out.println("还能做产品");
   }


   public void work(){
       this.code();
       this.pm();
   }

   public static void main(String[] args) {

       Adapter adapter = new Adapter();
       adapter.work();

   }

}

test result:

能写代码
还能做产品

2，对象适配器模式

源角色(Adaptee):

package com.objectadapter;
public class Adaptee {
   public void code(){
       System.out.println("能写代码");
   }
}

目标抽象角色(Target):

package com.objectadapter;
public interface Target {
public void code();
public void pm();
}

适配器角色(Adapter)

package com.objectadapter;

//Adpter：就是继承Target,继承Adaptee
public class Adapter implements Target {
   public Adaptee adaptee ;
//这里这个IT民工即能写代码，也能做产品,话说好多coder都喜欢这么yy来着
   public Adapter(Adaptee adaptee){
       this.adaptee = adaptee;
   }

   public void code() {
       // TODO Auto-generated method stub
       this.adaptee.code();
   }

   public void pm() {
       System.out.println("我还能做产品");
   }

   public void work(){
       this.code();
       this.pm();
   }

   public static void main(String[] args) {
       Adaptee adaptee = new Adaptee();
       Adapter adapter = new Adapter(adaptee);
       adapter.work();

   }

}
