匿名内部类中的接口如何工作？ [英] How does the interface in anonymous inner class work?

问题描述

interface MyInter {
    public void display();
}

class OuterClass8 {

    public static void main(String arg[]) {

        MyInter mi=new MyInter() {

            public void display() {
                System.out.println("this is anonymous class1");
            }
        };

        mi.display();
    }
}

据我所知，我们无法实例化界面那么这是怎么发生的呢？

As far as I know, we cannot instantiate an interface, so how did this happen?

推荐答案

你不能实例化一个接口，但你可以提供一个对象接口的引用实现接口的类，所以在代码中你实现接口并创建该类的对象并提供该类的引用。

You cannot instantiate an interface, but you can provide a reference of an interface to an object of the class implementing the interface, so in code you are implementing interface and creating an object of that class and give reference of that class.
