GoLang的物件導向

通過golang實現物件導向的過程， 以及golang的繼承關係

定義了動物， 定義了鳥類，魚類， 最後的對象是 燕子， Nimo

package mainimport "fmt"type Animal interface {    Eat()    Play()}type animal struct {    name string}type Bird interface {    Animal //匿名嵌入介面    Fly()}type bird struct {    animal //匿名嵌入繼承父親的name    wings  int}type Fish interface {    Animal    Swim()}type fish struct {    animal //整合父親的name    name   string    fin    int}func (a *animal) Eat() {    fmt.Println(a.name, "is eatting now")}func (a *animal) Play() {    fmt.Println(a.name, "is playing now")}func (b *bird) Fly() {    fmt.Println(b.name, "is flying now")}func (b *bird) Eat() { // 重寫了父親的吃的方法    fmt.Println(b.name, "is eatting too much")}func (f *fish) Swim() {    fmt.Println(f.name, "is swimming now")}func (f *fish) Eat() {    fmt.Println(f.name, "is etting now")}func main() {    fmt.Println("hello golang oo")    bird := bird{animal{"swallow"}, 2}    bird.Fly() // bird的特有方法,    "swallow is flying now"    bird.Eat() //重寫了父親的方法,  "swallow is eatting too much"    fish := fish{animal{"Clown Fish"}, "Nimo", 3}    fish.Play() // 繼承父親的方法， "Clown Fish is playing now"， 父親的name    fish.Eat()  // 重寫父親的方法， "Nimo is etting", 用父親的name    fish.Swim() // fish 特有的方法 "Nimo is swimming now";}
