Java中接口以及接口回调的简单使用

public class InterfaceDemo {

public static void main(String[] args){
    sendHttpRequests("你好，孤独的人！", new HttpRequests() {
        @Override
        public void success(String response) {
            System.out.println("访问成功了呢！");
        }

        @Override
        public void fail() {
            System.out.println("访问失败哦！");
        }
    });
}

public static void sendHttpRequests(String address, HttpRequests httpRequests){
    if (!address.isEmpty()){
        httpRequests.success(address);
    }else {
        httpRequests.fail();
    }
}

}

interface HttpRequests {
void success(String response);
void fail();
}
