Hi Jacob,

Without seeing all your code, it's really difficult to say why. I don't see the before variable being set, but if you are getting the same name for the placeholders, then something is off with that variable and how it's being set. Review the video and double check all your code (the problem is not with the line you shared). If you are using Treehouse's Workspaces, you can share a snapshot of your Workspace.

Hope you get it figured out. :) :dizzy:

I had a similar question about the flip from printf to print and println

I have used print and println from System.out .... etc.

printf seems to work like c's call (where I would concatenate variables and literal strings, printf in Java looks more like C.

Could you explain reasoning? Has printf in Java been deprecated?
