reflect.TypeOf() Function in Golang with Examples Last Updated : 28 Apr, 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.TypeOf() Function in Golang is used to get the reflection Type that represents the dynamic type of i. To access this function, one needs to imports the reflect package in the program. Syntax: func TypeOf(i interface{}) Type Parameters: This function takes only one parameters of interface( i ). Return Value: This function returns the reflection Type. Below examples illustrate the use of above method in Golang: Example 1: C // Golang program to illustrate // reflect.TypeOf() Function package main import ( "fmt" "reflect" ) // Main function func main() { tst1 := "string" tst2 := 10 tst3 := 1.2 tst4 := true tst5 := []string{"foo", "bar", "baz"} tst6 := map[string]int{"apple": 23, "tomato": 13} // use of TypeOf method fmt.Println(reflect.TypeOf(tst1)) fmt.Println(reflect.TypeOf(tst2)) fmt.Println(reflect.TypeOf(tst3)) fmt.Println(reflect.TypeOf(tst4)) fmt.Println(reflect.TypeOf(tst5)) fmt.Println(reflect.TypeOf(tst6)) } Output: string int float64 bool []string map[string]int Example 2: C // Golang program to illustrate // reflect.TypeOf() Function package main import ( "fmt" "io" "os" "reflect" ) // Main function func main() { // use of TypeOf method tt := reflect.TypeOf((*io.Writer)(nil)).Elem() fileType := reflect.TypeOf((*os.File)(nil)) fmt.Println(fileType.Implements(tt)) } Output: true Comment More infoAdvertise with us Next Article reflect.TypeOf() Function in Golang with Examples S SHUBHAMSINGH10 Follow Improve Article Tags : Go Language Golang-reflect Similar Reads reflect.Type() 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.
