实例讲解JAVA 适配器模式

public class Target {

 System.out.println("普通请求");
 }
}

public class Adaptee {
 public void specialRequest(){
 System.out.println("特殊请求");
 }
}

public class Adapter extends Target{
 private Adaptee adaptee = new Adaptee();//建立一个私有的Adaptee对象
 
 @Override
 public void request() {
 //这样就可以把表面上调用request()方法变成实际调用的specialRequest()
 adaptee.specialRequest();
 }
}

public class Test {
 public static void main(String[] args) {
　　　　 //对main方法来说，调用的就是Target的request() 
　　　　 Target target = new Target();
 target.request();
 }
}
