strings.Join() Function in Golang concatenates all the elements present in the slice of string into a single string. This function is available in the string package.
Syntax:
func Join(s []string, sep string) string
Here, s is the string from which we can concatenate elements and sep is the separator which is placed between the elements in the final string.
Return Value: It returns a string.
Example 1:
// Golang program to illustrate the // use of strings.Join Function package main // importing fmt and strings import ( "fmt" "strings") // calling main method func main() { // array of strings. str := []string{"Geeks", "For", "Geeks"} // joining the string by separator fmt.Println(strings.Join(str, "-")) } |
Output:
Geeks-For-Geeks
Example 2:
// Golang program to illustrate the // use of strings.Join Function package main // importing fmt and strings import ( "fmt" "strings") // calling main method func main() { // array of strings. str := []string{"A", "Computer-science", "portal", "for", "Geeks"} // joining the string by separator in middle. fmt.Println(strings.Join(str, " ")) } |
Output:
