Casting non-numeric strings to integers usually produces a 0/truncation in programs, at the first illegal character: E.g. Typically sample 12345 0 or null 123apple456 123 45 45 (spaces ok) 3 7 9 3 (internal spaces truncate) Though you may get an exception, it is generally assumed you know the difference between string and numeric types.

As you said, you want a number and the program is in fact expecting a nextInt And apple is not a number XD
