Go Language: Convert byte array to string

Below statement is used to convert byte array to string.

Approach 1: Using string()

Syntax

msg := string(byteArray[:])

App.go

package main

import "fmt"

func main() {
	arr := []byte{97, 98, 99, 100, 101, 102, 103}

	msg := string(arr)

	fmt.Println("msg : "

, msg) }

Output

msg :  abcdefg

Approach 2: Using fmt.Sprintf

Syntax

msg := fmt.Sprintf("%s", arr)

App.go

package main

import "fmt"

func main() {
	arr := []byte{97, 98, 99, 100, 101, 102, 103}

	msg := fmt.Sprintf("%s", arr)

	fmt.Println("msg : ", msg)

}

Approach 3: Using bytes.NewBuffer

Syntax

msg := bytes.NewBuffer(byteArray).String()

App.go

package main

import (
	"bytes"
	"fmt"
)

func main() {
	byteArray := []byte{97, 98, 99, 100, 101, 102, 103}

	msg := bytes.NewBuffer(byteArray).String()

	fmt.Println("msg : ", msg)

}
