Answer 1

nextLine() <- with uppercase 'L'
nextline() <- with lowercase 'L'

We must call methods by their name correctly. A difference of a letter, or letter case matters for case sensitive languages.

Answer 2

Line 7:
swallow.nextLine(), not swallow.nextline()

Java is a case sensitive language, must take care to minimize typos

Answer 3

@Ipang what's different ?
