Class in Golang

Golang does not have a keyword class . But it does not limit you to define a class in Golang. You can define a class which is defining variables and methods of a class, by providing set of methods on the common type.

For example, you can define a class by defining a struct and implementing methods on the struct type. And this struct will be analogous to a class concept.

Example ? Golang Class

In the following example, we will define a class in golang using Golang structures.

example.go

package main import "fmt" // struct definition type Student struct {

name string rollNumber int } // associate method to Strudent struct type func (s Student) PrintDetails() { fmt.Println("Student Details\n---------------") fmt.Println("Name :", s.name) fmt.Println("Roll Number :", s.rollNumber) } func main() { var stud1 = Student{name:"Anu", rollNumber:14} stud1.PrintDetails() }

Output

Student Details --------------Name : Anu Roll Number : 14

The Student struct is analogous to a class below provided in pseudo code.

Pseudo Code

class Student{ name rollnumber function PrintDetails(){ // print details using this.name, this.rollnumber }

}
