文件名称```interface.go```,代码如下:
```
package main

import (
	"fmt"
)
type USB interface {
	working()
	reject()
}
type USB1 interface {
	working()
	reject()
}
type Phone struct{
}
type Cameron struct{
}
type Computer struct{
}
// phone 实现接口working
func (p Phone) working(){
	fmt.Println("phone p start working.")
}
func (p Phone) reject(){
	fmt.Println("phone p will be  rejected.")
}
func (c Cameron) working(){
	fmt.Println("cameron c start working.")
}
func (c Cameron) reject(){
	fmt.Println("cameron c reject.")
}
// Computer stuct 's func work ,not implement the interface
func (c Computer) work(usb USB){
	usb.working()
	usb.reject()
}

type MyInt int
func (i MyInt) working(){
	fmt.Println(" customer type  working() function.")
}

func (i MyInt) reject(){
	fmt.Println(" customer type reject() function.")
}

func main(){
	c := Computer{}
	car := Cameron{}
	ph := Phone{}
	c.work(car)
	c.work(ph)
	fmt.Println("===========================next======================.")
	var usb USB
	var myInt MyInt //MyInt 实现了接口接口的working,reject方法，但是没有指明哪个接口
	usb = myInt //赋值给接口，包含方法，myInt需要实现该接口的所有的方法。
	usb.reject()
	usb.working()
	myInt.reject()
	myInt.working()
}
```
