Golang 之 interface接口全面理解

func (c *Cat) Speak() string {

    return "Meow!"

}

运行上述代码，会得到如下错误：

cannot use Cat literal (type Cat) as type Animal in array or slice literal:

    Cat does not implement Animal (Speak method has pointer receiver)

CatAnimal*Catnew(Cat)&Cat{}

animals := []Animal{Dog{}, new(Cat), Llama{}, JavaProgrammer{}}

*DogDogSpeak()

animals := []Animal{new(Dog), new(Cat), Llama{}, JavaProgrammer{}}

func (t T)MyMethod(s string) {

    // ...

}
