Go Language Object-oriented

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

The go language can declare new types through structs

Create a new type person

typestruct {    string    int}var'liming'p1.age = 18

Create a new type student, you can introduce the person all characters De Yin by anonymous field student

typestruct {    Person  //隐式引入    string    string}s1 := Student{Person{'zhangliang',23'hign school','new name'}s1.age   //23  可直接访问Person的字段s1.name  //new name 最外层优先访问，重载//zhangliang 通过匿名字段访问

Add a recipient struct to a function, or add a method to a struct

//此处传递是按值传递的，操作的是副本，若receiver为指针，则按引用传递，操作的是原实例对象boolean {    if18 {  //可以直接访问struct的字段        returntrue    }    returnfalse} s1.isAdult()  //trueintboolean {    s.age = newAge }s1.changeAge(23)

Method is the same as the inheritance of the field, all through the anonymous field

type HignSchoolStudet {    Student    string}//可函数重载funcint) boolean {    h.age = newAge + 12}h1 := HignSchoolStudet{Student{Person{'zhangliang',23'hign school'},'math'}

The interface interface, which provides a combination of common methods, provides a dynamic type

type people interface {changeage ()}
    var i  peoplei  = S1S1.  Changeage () i  = H1h1.  Age
