24、Go语言中的OOP思想

1、是什么？

OOP：面向对象

Go语言的解构体嵌套
	1、模拟集成性：is - a
		type A struct {
			field
		}
		type B struct {
			A // 匿名字段
		}
	这种方式就会存在变量提升
	2、模拟聚合关系：has - a
		type C struct {
			field
		}
		type D struct {
			c C // 聚合关系
		}
	这种方式就需要访问结构体变量来设置相应的值

2、代码示例

package main

import "fmt"

func main() {
	p1 := Person{name: "张三", age: 18}
	fmt.Println(p1)

	s1 := Student{Person: Person{name: "ly", age: 20}, school: "北京大学", name: "小明"}
	fmt.Println(s1)

	var s2 Student
	s2.Person.name = "李四"
	s2.Person.age = 22
	s2.school = "清华大学"
	s2.name = "小花"
	fmt.Println(s2)

	var s3 Student
	s3.Person.name = "王五"
	s3.age = 23
	s3.school = "武汉大学"
	s3.name = "小张"
	fmt.Println(s3)
}

type Person struct {
	name string
	age  int
}

type Student struct {
	Person
	school string
	name   string
}
