本文實例講述了Go語言使用組合的方式實現多繼承的方法。分享給大家供大家參考。具體實現方法如下：
在大多數面向對象的編程語言中多繼承都是不支持的。因為在基于class的體系中，多繼承極大地增加了編譯器的復雜性。
Go語言使用組合的方式實現繼承，因此也可以很簡單的實現多繼承。
復制代碼代碼如下:
//使用組合的方式實現多繼承
type Phone struct{}
func (p *Phone) Call() string {
return "Ring Ring"
}
type Camera struct{}
func (c *Camera) TakeAPicture() string {
return "Click"
}
//多繼承
type CameraPhone struct {
Camera
Phone
}
func structTest0803() {
cp := new(CameraPhone)
fmt.Println("Our new CameraPhone exhibits multiple behaviors ...")
fmt.Println("It exhibits behavior of a Camera: ", cp.TakeAPicture())
fmt.Println("It works like a Phone too: ", cp.Call())
/*Output:
Our new CameraPhone exhibits multiple behaviors ...
It exhibits behavior of a Camera: Click
It works like a Phone too: Ring Ring
*/
}
type Phone struct{}
func (p *Phone) Call() string {
return "Ring Ring"
}
type Camera struct{}
func (c *Camera) TakeAPicture() string {
return "Click"
}
//多繼承
type CameraPhone struct {
Camera
Phone
}
func structTest0803() {
cp := new(CameraPhone)
fmt.Println("Our new CameraPhone exhibits multiple behaviors ...")
fmt.Println("It exhibits behavior of a Camera: ", cp.TakeAPicture())
fmt.Println("It works like a Phone too: ", cp.Call())
/*Output:
Our new CameraPhone exhibits multiple behaviors ...
It exhibits behavior of a Camera: Click
It works like a Phone too: Ring Ring
*/
}
希望本文所述對大家的Go語言程序設計有所幫助。
