Why is hasNext() method in java returns true without even adding anything in stdin?

Question

I was working on a program in java to known the EOF of the input file
When doing this the following code is a bit confusing

Scanner in=new Scanner(System.in);
System.out.println(in.hasNext());

This code outputs "true" even without taking any input?

Answer 1

Are you sure? Am getting false only.. Check it again once..

Answer 2

Thank you Martin Taylor,

My test case input is a file input in hackerrank I am getting the answer required but i am a little confused on how i got it.

Now I came to know that giving input to Scanner class System.in takes all inputs and we assign variables in required manner .
