This is a creation in Article, where the information may have evolved or changed.

The following code is validated by the go1.5

Package Main

Import (

"FMT"

)

Type person struct {

Name string

Age  int

Tel  string

}

Type Student struct {

person//has another field

School string

}

Func (P *person) Print () {

Fmt. Printf ("print\n")

P.hello ()//Hello to Person

}

Defines a method for passing values on person

Func (P *person) Hello () {

P.tel = "186"

Fmt. Printf ("Person My name was%s, and my tel number is%s\n", P.name, P.tel)

}

Polymorphic

Func (P *student) Hello () {

P.tel = "0117"

Fmt. Printf ("Student My name is%s, and my tel number is%s\n", P.name, P.tel)

}

Func Main () {

Anna: = new (Student)

Anna. Person.name = "Jim"

Anna.tel = "12345678"

Anna. Hello ()  //student My name is Jim, and my tel number is 0117

Anna. Person.hello ()  //person My name is Jim, and my tel number is 186

Anna. Print ()  //print
                  Here in C + + it calls student's Hello interface
