Golang learning 面向对象 多态

通过interface 实现多态

type Cat struct {
    Animal
    teeth string "牙"
    leg  int
}

type Dog struct {

    Animal
    teeth string "牙"
    leg  int
}

type NewAction interface {

    run()

}


func (c Cat) run(){

    fmt.Print("\ncat----run")

}


func (c Dog) run(){

    fmt.Print("\nDog----run")

}

func main() {

        cat := Cat{}
    dog := Dog{}
    animalRun(cat)
    animalRun(dog)
}

打印  
cat----run
Dog----run
