Question

I am trying to work on some stuff using the Scanner for input, but for some reason, the scanner is failing me.

I have the following code running, nothing complex:

while(scan.hasNextLine())
    {
        System.out.println(scan.nextLine());
    }

Just as a test bed to make sure everything is being input correctly. If I copy my test material, say

5
4
3
2
1

The output omits the last line. I am pretty sure that it is because nextLine will only return a string if there is a string after it, even if it is empty, but I need it to work this way for the way I will eventually input the data to work. Does anyone know how I can fix this? My only guesses were to either use something other that scanner or to somehow append an empty string to the end of the input, but I wasn’t sure how to do the second one, and I didn’t think a different scanner-like thing would work. Thanks in advance!

Answer 1

Your last line MIGHT not have a “enter” char. So it does not treat it as the end of line. Try

> 5
> 4
> 3
> 2
> 1
