Go Class
Go does not have a keyword class
. But it does not limit us to define a class in Go. We can define a class in a way which is similar to defining variables; and define methods of a class, by providing set of methods on the common type.
For example, we can define a class by defining a struct and implement methods on the struct type. And this struct will be analogous to a class concept.
Example
In the following example, we will define a class in golang using Go 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 } }

Conclusion
In this Golang Tutorial, we learned how to word around a Class concept is in Go, with the help of examples.
