Golang : Implement getters and setters

Because Golang does not provide automatic getters and setters, Go programmers will have to implement the getters and setters themselves. This is a quick tutorial on how to set and get identifiers value in a struct.

 package main

 import (
  "fmt"
 )

 type Person struct {
  Name  string // exported identifier
  email string // un-exported identifier... need Set and Get methods for help
 }

 func (p *Person) SetEmail(email string) {
  p.email = email
 }

 func (p Person) GetEmail() string {
  return p.email
 }

 func main() {

  employee := Person{}
  //employee := new(Person) // new object

  
  fmt.Println(employee)

  // set data to private variable via SetEmail method

  employee.SetEmail("[email protected]")

  employee.Name = "Adam"

  
  fmt.Println(employee)

  // Retrieve data from private variables via GetEmail method
  fmt.Println(employee.GetEmail())

  fmt.Println(employee.Name)

 }

Output :

{ }

{Adam [email protected]}

[email protected]

Adam
