Golang入门到项目实战 | golang继承

golang本质上没有oop的概念，也没有继承的概念，但是可以通过结构体嵌套实现这个特性。

例如

package main

import "fmt"

type Animal struct 
    name string
    age  int


func (a Animal) eat() 
    fmt.Println("eat...")


func (a Animal) sleep() 
    fmt.Println("sleep")


type Dog struct 
    Animal


type Cat struct 
    Animal


func main() 
    dog := Dog
        Animal
            name: "dog",
            age:  2,
        ,
    

    cat := Cat
        Animal
            name: "cat",
            age:  3,
        ,
    

    dog.eat()
    dog.sleep()

    cat.eat()
    dog.sleep()

运行结果

[Running] go run "/Users/guoliang/SynologyDrive/软件开发/go/golang入门到项目实战/goproject/360duote.com/pro01/test.go"
eat...
sleep
eat...
sleep
