In Go language, it is allowed to create two or more methods with the same name in the same package, but the receiver of these methods must be of different types. This feature does not available in Go function, means you are not allowed to create same name methods in the same package, if you try to do, then the compiler will throw an error.


func(reciver_name_1 Type) method_name(parameter_list)(return_type){
// Code

func(reciver_name_2 Type) method_name(parameter_list)(return_type){
// Code

Let us discuss this concept with the help of the examples:

Example 1:

// Go program to illustrate how to
// create methods of the same name
package main
import "fmt"
// Creating structures
type student struct {
    name   string
    branch string
type teacher struct {
    language string
    marks    int
// Same name methods, but with
// different type of receivers
func (s student) show() {
    fmt.Println("Name of the Student:",
    fmt.Println("Branch: ", s.branch)
func (t teacher) show() {
    fmt.Println("Language:", t.language)
    fmt.Println("Student Marks: ", t.marks)
// Main function
func main() {
    // Initializing values
    // of the structures
    val1 := student{"Rohit", "EEE"}
    val2 := teacher{"Java", 50}
    // Calling the methods


Name of the Student: Rohit
Branch:  EEE
Language: Java
Student Marks:  50

Explanation: In the above example, we have two same name methods, i.e, show() but with different type of receivers. Here first show() method contain s receiver which is of the student type and the second show() method contains t receiver which is of the teacher type. And in the main() function, we call both the methods with the help of their respective structure variables. If you try to create this show() methods with the same type of receiver, then the compiler throws an error.

Example 2:

// Go program to illustrate how to
// create the same name methods
// with non-struct type receivers
package main
import "fmt"
type value_1 string
type value_2 int
// Creating same name function with
// different types of non-struct receivers
func (a value_1) display() value_1 {
    return a + "forGeeks"
func (p value_2) display() value_2 {
    return p + 298
// Main function
func main() {
    // Initializing the values
    res1 := value_1("Geeks")
    res2 := value_2(234)
    // Display the results
    fmt.Println("Result 1: ", res1.display())
    fmt.Println("Result 2: ", res2.display())


Result 1:  GeeksforGeeks
Result 2: 532
