go 结构体继承,及其方法

package main

import (
	"fmt"
)


type Animal struct {
	Name string  
	Sex string
}


func (a *Animal)Talk(){
	fmt.Printf("Animal is talk, i'm %s\n", a.Name)
}
func (a *Animal)Eat(){
	fmt.Println("dog Animal is eat")
}


type PuruAnimal  struct{}

type Dog  struct{
	Feet string
	//Animal         // 值类型
	*Animal          // 指针类型
	*PuruAnimal      // 指针类型
}


func (p *PuruAnimal)Talk(){
	fmt.Println("puru dongwu is talking\n")
}

func (p *PuruAnimal)Walk(){
	fmt.Println("puru dongwu is walking\n")
}


func (d *Dog)Talk(){
	fmt.Printf("dog %s is talking\n",d.Name)
}


func (d *Dog)Eat(){
	fmt.Printf("dog %s is eat\n",d.Name)
}


func main(){
	var d *Dog = &Dog{
		Feet:"four feet",
		Animal:&Animal{
			Name:"旺财",
			Sex:"公",
		},
		PuruAnimal:&PuruAnimal{},
	}

	d.Eat()
	d.Talk()
	d.Name = "小黑"
	d.Sex ="公"
	d.Eat()
	d.Talk()

	d.Animal.Talk()
	d.PuruAnimal.Talk()
	d.Talk()
	d.Walk()
}

输出:

dog 旺财 is eat
dog 旺财 is talking
dog 小黑 is eat
dog 小黑 is talking
Animal is talk, i'm 小黑
puru dongwu is talking

dog 小黑 is talking
