How do I implement the Stringer interface in Go?

Go, Stringer interface, fmt package, struct, method

This example demonstrates how to implement the Stringer interface in Go which allows you to define a string representation for your struct types.


        package main

        import (
            "fmt"
        )

        // Person struct that implements the Stringer interface
        type Person struct {
            Name string
            Age  int
        }

        // String method to implement the Stringer interface
        func (p Person) String() string {
            return fmt.Sprintf("Name: %s, Age: %d", p.Name, p.Age)
        }

        func main() {
            person := Person{Name: "John Doe", Age: 30}
            fmt.Println(person) // Output: Name: John Doe, Age: 30
        }
