Question about the task Minimum of three numbers
Java Syntax, Level 2, Lesson 8
Under discussion
not getting the correct c min value and code seems to work without { } brackets as well.I just need a little help understanding this and if I should be writing it any differently. I see other examples with " { } " brackets around the inside of the if statements and I see double boolean && that im a little unsure of how to use as well.

Works flawlessly, follows listed rules perfectly, but won't pass the "allowed operators" criteria I should start by mentioning that I know Wei Cui posted something that will pass in another person's question, but if I just copy and paste that I won't be learning why my own code is not validating. I can't seem to find any of the listed requirements I'm not in line with, and it works for all value
