strings.SplitAfter() Function in Golang
strings.SplitAfter() is a built-in function in Golang that is used to break a string into a slice. SplitAfter is different from other Split functions. Here, we slice a given string into substrings after each instance of separators and it returns a slice of those substrings.
Syntax
func SplitAfter(S String, sep string) []string
Where s is the given string and sep is the separator string.
Example 1
Consider the following example −
package main import ( "fmt" "strings" ) func main() { // Intializing the Strings x := "Golang Program of SplitAfter Function" y := "1.2.3.4.5.6.7.8" // Display the Strings fmt.Println("String 1: ", x) fmt.Println("String 2: ", y) // Using the SplitAfter z := strings.SplitAfter(x, "r") w := strings.SplitAfter(y, ".") // Display the SplitAfter Output fmt.Println("\nSplitAfter for String 1 \n:", z) // range() Function for v := range(w) { fmt.Println("\nString 2 Range:", w[v]) } }
Output
It will generate the following output −
String 1: Golang Program of SplitAfter Function String 2: 1.2.3.4.5.6.7.8 SplitAfter for String 1 : [Golang Pr ogr am of SplitAfter Function] String 2 Range: 1. String 2 Range: 2. String 2 Range: 3. String 2 Range: 4. String 2 Range: 5. String 2 Range: 6. String 2 Range: 7. String 2 Range: 8
Example 2
Let us take another example −
package main import ( "fmt" "strings" ) func main() { // Intializing the Strings str1 := "012344564784891423156" str2 := "Golang SplitAfter String Function" str3 := "1&2&3&4&5&6&7&8" // Display the Strings fmt.Println("String 1: ", str1) fmt.Println("String 2: ", str2) fmt.Println("String 3: ", str3) // Using the SplitAfter Function res1 := strings.SplitAfter(str1, "4") res2 := strings.SplitAfter(str2, "Split") res3 := strings.SplitAfter(str3, "&") res4 := strings.SplitAfter(str2, " ") res5 := strings.SplitAfter(str2, "Go") // Display the SplitAfter Output fmt.Println("SplitAfter for String 1:", res1) fmt.Println("SplitAfter for String 2:", res2) fmt.Println("SplitAfter for String 3:", res3) fmt.Println("SplitAfter for String 2:", res4) fmt.Println("SplitAfter for String 2:", res5) }
Output
It will generate the following output −
String 1: 012344564784891423156 String 2: Golang SplitAfter String Function String 3: 1&2&3&4&5&6&7&8 SplitAfter for String 1: [01234 4 564 784 8914 23156] SplitAfter for String 2: [Golang Split After String Function] SplitAfter for String 3: [1& 2& 3& 4& 5& 6& 7& 8] SplitAfter for String 2: [Golang SplitAfter String Function] SplitAfter for String 2: [Go lang SplitAfter String Function]
