Answer 1

Yes, single scanner is enough for all data types. You'll just have to call different methods for different data types. (like nextInt() for int, nextDouble() for double etc.)

Answer 2

Use one scanner for all inputs. Change the line of money's input to:
money = a.nextInt();
Also remove the declaration of m. :)

Answer 3

can't we call another scanner with defferent variable in the same sintax? is that a single scanner enough for all data types? thanks again for clarifying.
