10.Go语言-面向对象简单了解

1.面向对象

1.1匿名字段

package main

import "fmt"

type Person struct {
	name string
	sex string
	age int
}

type Student struct {
	Person
	id int
	addr string
}

func main() {
	s1:=Student{Person{"Simi","man",20}, 1, "china"}
	fmt.Print(s1)
	s2:=Student{Person:Person{"alex","woman",30}}
	fmt.Print(s2)
	s3 := Student{Person:Person{name:"wming"}}
	fmt.Println(s3)
}

1.2接口

• 指针匿名字段

package main

import "fmt"

type Person struct {
	name string
	age int
	sex string
}

type mystr string

type Student struct {
	*Person
	int
	mystr
}

func main() {
	s1:=Student{&Person{"xujk",20,"man"},22,"hello world"}
	fmt.Println(s1)
	fmt.Println(s1.name)
	fmt.Println(s1.Person.name)
}


{0xc000066180 22 hello world}
xujk
xujk
