Removed line 29. Now only the sixth point does not work.

useful

Unfortunately I do not know Codegym's test cases but if they use something like 4chan it will become @chan while the comparison word is lowercased using a String method that leaves the @ untouched. So I'd rework lines 66 - 69 and use either String.toLowerCase() or the static counterpart from the Character class head = Character.toLowerCase(head) or, if you stay with strings, use String.equalsIgnoreCase() When I make this change, then my testcase

Okinawa rialto 4chan Antonow-an-124

works perfectly, too.
