Reflection of Pointer and Non-Pointer Types in Go

reflect.Type.Elem() can return the type of the element, for example, for pointer types, it returns the type without the pointer.
reflect.Value.Elem() is used to obtain a reference to the value that the pointer points to.

type name struct {
}

func (n name) Print(str string) {

}

func main() {
	var n interface{} = &name{}
	t := reflect.TypeOf(n)
	var na interface{}

	// Instantiate
	if t.Kind() == reflect.Ptr {
		// Dereference pointer type
		elem := t.Elem()
		obj := reflect.New(elem)
		na = obj.Elem().Interface()
	} else {
		obj := reflect.New(t)
		na = obj.Elem().Interface()
	}

	nn := na.(name)
	nn.Print("aaa")
}
