The
!is a boolean NOT operator, defined in Section 15.15.6 of the Java Language Specification. It makestruefalseandfalsetrue. So what that return statement is doing is returning a boolean which will betrueif eitherweekdayisfalse(“not weekday”) or (||)vacationistrue. It will befalseifweekdayistrueandvacationisfalse.
