Golang entry struct inheritance, nesting

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

Package Mainimport "FMT" type jocongmin struct{name stringhome stringwant String}func (J *jocongmin) Sayname () string{
  
   //here defines the method is to expand the method, is the inheritance of jocongmin this struct, that is, the struct more than a say. method, you can call return by jocongmin this struct instance "My name is" +j.name}func (J *jocongmin) Sayhome () String{return "My Home In" +j.home}func (J * jocongmin) saywant () String{return "My favorite is" +j.want}func main () {var jocongmin jocongminjocongmin.name= "Week smart" jocongmin.
