仿造WindowAdapter写了一个程序，为啥不成功呢

[hitzsf]

public class MyScrollPane {
    public void show(){
       new WindowAdSub().open1();
       new WindowAd() {
            @Override
            public void open1(){
                System.out.print("hello2");//此处没有打印，为啥？，同样都是抽象类，同样都是匿名内部写法，
            }           
       };
    }
      public static void main(String [] args){
          new MyScrollPane().show();
               
      }
      
 
  class WindowAdSub extends WindowAd{
    public void open1(){
        System.out.print("hello1");
    }
  }

}
/////////////////////////////////////////////////
    interface WindowE{
        public void open1();
        public void open2();
        public void open3();
    }

 abstract  class WindowAd implements WindowE{
       
        public void open1(){};
       
        public void open2(){};
       
        public void open3(){};
}

注意看我的注释

public class MyScrollPane {
    public void show(){
       new WindowAdSub().open1();
       new WindowAd() {
            @Override
            public void open1(){
                System.out.print("hello2");//此处没有打印,是因为这只是重写一个方法，又不是重写并且调用
                                           //你需要自己去调用它
            }
       }.open1();
    }
      public static void main(String [] args){
          new MyScrollPane().show();

      }


  class WindowAdSub extends WindowAd{
    public void open1(){
        System.out.print("hello1");
    }
  }

}
/////////////////////////////////////////////////
    interface WindowE{
        public void open1();
        public void open2();
        public void open3();
    }

 abstract  class WindowAd implements WindowE{

        public void open1(){};

        public void open2(){};

        public void open3(){};
}

楼上正解
因为楼主是作声明
未调用方法

呵呵，谢谢
