reflect.New() Function in Golang with Examples Last Updated : 03 May, 2020 Comments Improve Suggest changes Like Article Like Report Go language provides inbuilt support implementation of run-time reflection and allowing a program to manipulate objects with arbitrary types with the help of reflect package.The reflect.New() Function in Golang is used to get the Value representing a pointer to a new zero value for the specified type. To access this function, one needs to imports the reflect package in the program. Syntax: func New(typ Type) Value Parameters: This function takes the following parameters: typ : This parameter is the Type. Return Value: This function returns a Value representing a pointer to a new zero value for the specified type. Below examples illustrate the use of above method in Golang : Example 1: C // Golang program to illustrate // reflect.New() Function package main import ( "fmt" "reflect" ) // Main function func main() { t := reflect.TypeOf(5) //use of ArrayOf method arr := reflect.ArrayOf(4, t) inst := reflect.New(arr).Interface().(*[4]int) for i := 1; i <= 4; i++ { inst[i-1] = i*i } fmt.Println(inst) } Output: &[1 4 9 16] Example 2: C // Golang program to illustrate // reflect.New() Function package main import ( "fmt" "reflect" ) type Geek struct { A int `tag1:"First Tag" tag2:"Second Tag"` B string } // Main function func main() { greeting := "GeeksforGeeks" f := Geek{A: 10, B: "Number"} gVal := reflect.ValueOf(greeting) fmt.Println(gVal.Interface()) gpVal := reflect.ValueOf(&greeting) gpVal.Elem().SetString("Articles") fmt.Println(greeting) fType := reflect.TypeOf(f) fVal := reflect.New(fType) fVal.Elem().Field(0).SetInt(20) fVal.Elem().Field(1).SetString("Number") f2 := fVal.Elem().Interface().(Geek) fmt.Printf("%+v, %d, %s\n", f2, f2.A, f2.B) } Output: GeeksforGeeks Articles {A:20 B:Number}, 20, Number Comment More infoAdvertise with us Next Article reflect.New() Function in Golang with Examples S SHUBHAMSINGH10 Follow Improve Article Tags : Go Language Write From Home Golang-reflect Similar Reads reflect.NewAt() Function in Golang with Examples Go language provides inbuilt support implementation of run-time reflection and allowing a program to manipulate objects with arbitrary types with the help of reflect package.
