Java Local Development Environments Advanced Tooling Finishing TreeStory

OK guys...BUMMER: TreeStory(3)...adding to the pile. (sorry)

Ive been up and down this area of the forums for hours looking for a solution, but now its time to hand it over and hope someone can help. Just like a lot of people before me, Ive been having trouble with the third parameter for finishing TreeStory. I can see in the preview that the final story does actually get printed.

Looks like its not actually a problem with the output, and the error i'm getting is misleading. But it is hard to figure out when it runs well in IntelliJ.

on the upside, frustrating times like this sure do seem to help the learning process....in the end....please help me XD

#  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

OK figured it out. might as well share.

I didnt realise I could use the mReader object in all of my methods that require input from the user. I was creating new BufferedReader objects for promptForWord and promptForTemplate. Which WORKS FINE in IntelliJ but its just...not....gooood enough for Craig ;-)
