Question about the task Good or bad?
Java Syntax, Level 3, Lesson 7
Under discussion
It appears I match all the criteria, can anybody spare a hint?I've met all the criteria. If a < 5, displays less than 5. Else displays number is greater than 5. Instructions say nothing about whether or not number is actually 5, as is the case with the third call of the compare method. I can fix this with an "else if" but I'm not specifically asked to.
