Why is the answer "java.io"?

Question

A challenge question asked what should be imported to accept user input;
Options were:
java.nio
java.util
java.io
and some other one.
I chose java.util but failed it, why is the correct answer java.io(is it BufferedReader they mean and if so, that means there are two answers right?)

Answer 1

Lemme guess: (Not a java programmer though)
Is it because
io means input/output
whereas util is utility
I think io mainly deals with input/output of files, user input etc
while util deals with utility objects like ArrayList, HashMap, Methods etc..

Answer 2

@Cool Codin,by java.util it means java.util.Scanner, Scanner class is for taking input, which is why I was confused, will report the question as Gordie said
