Error in code

Question

This code runs in NetBeans, but for some reason here https://code.sololearn.com/cZFMG9VSYEUg/#java no.

Thanks.

Answer 1

Try to add at the begining

import java.util.Scanner;

and follow debugging ;-)

Answer 2

Maybe he did not copy the import from netbeans to playground.

Answer 3

How did it work on Netbeans then?
