Re: [mooc.fi] import java.util.Scanner; - Unused import ??

[Jarmo Isotalo]

You haven't declared variable reader. Thus the Cannot find symbol from word reader.

And what comes for the Unused import java.util.Scanner;  you don't have any variables which type is Scanner, thus the import is unused.

So here you are missing the declaration / initialization of the variable reader. Something like this.

Scanner reader = ... ;

Hi,

The first line import.java.util.Scanner; is not working for me in exercise 36. The helper just says its a "Unused import". Due to this the program can't for example find the reader part for    int number = Integer.parseInt(reader.nextLine()); . It just says "Cannot find a symbol".

Anyone had same kind of problems? It works for me in all the other exercises so I can't figure out why is it this way in that one?
