1,885 PointsMy code does everything asked in pseudo-tests and works on my machine but is not working as submitted.
Could someone point out to me what I'm doing wrong? It does everything asked.

# This is essentially what I am testing
1. The user is prompted for a new string template (the one with the double underscores in it).
a. The prompter class has a new method that prompts for the story template, and that method is called.
2. The user is then prompted for each word that has been double underscored.
a. The answer is checked to see if it is contained in the censored words.
User is continually prompted until they enter a valid word
3. The user is presented with the completed story

231,261 PointsDid you try running the preview? It shows this compiler error:
JavaTester.java:77: error: unreported exception IOException; must be caught or declared to be thrown
Main.main(null);
^
1 error
So you still have one job left to do (catch the error in "Main" instead of throwing it). Otherwise, it looks good!

1,885 PointsThank you. Do you know why that is? I see other methods throw the exception and it doesn't cause this problem. Is it because I am throwing an exception in the main method?

231,261 PointsYou've seen this in other challenges (it may be an issue because of how the challenge tests it)?
