objectsobjectsobjects一 什么是objects我们通常做查询操作的时候，都是通过 模型名字.objects 的方式进行操作。其实 模型名字.objects是一个 django.db.models.manager.Manager 对象，而 Manager 这个类是一个“空壳”的类，他本身是没有任何的属性和方法的。他的方法全部都是通过 Python 动态添加的方式，从 QuerySet 类中拷贝过来的。示例图如下：所以我们如果想要学习 ORM 模型的查找操作，必须首先要学会 Quer

The simple types of JavaScript are numbers, strings, booleans (true and false), null,and undefined. All other values are objects. Numbers, strings, and booleans areobject-like in that they have methods, but they are immutable. Objects in JavaScript are mutable keyed collections. In JavaScript, array

# 如何实现“java is not a functional interface”
## 概述
在Java中，函数式接口（Functional Interface）是只包含一个抽象方法的接口。如果一个接口包含多个抽象方法，那么它就不是函数式接口。在本文中，我将向你介绍如何实现“java is not a functional interface”。
## 实现步骤
