Answer 1

@alisa :
Using multiple scanners on the same stream is the underlying problem. Scanners can (and will) consume the stream - this may (will) lead to unexpected side-effects. Best not to do it.

If the input is closed, then the input (but Strings have no close method) is closed for everyone - and that's not much fun for anyone.

P.S. Try to avoid it ^^

Answer 2

Please don't make two objects of one Scanner class. It would cause an error. Instead, try to get two inputs with only one object. Now the code works perfect :
