2,064 PointsPrompt for story or not to prompt for story
Hey there!
Tried to complete this challenge in many ways without success.
I would also like to point out that many instructions and hints, throughout the course, are not very specific. Maybe its just me. Also i had the tester complain about throws IOException whenever it is beside main.
Nonetheless, please keep up with the great job, i've learned alot!

String story = null;
try {
story = promptForStory.promptForStory();
} catch (IOException e) {
e.printStackTrace();
}
Template tmpl = new Template(story);
promptForStory.run(tmpl);
List<String> fakeResults = Arrays.asList("friend", "talented", "java programmer", "high five");
}

# 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

Treehouse TeacherHmmm... how do they know what word they are typing in?
System.out.println("Please insert a word as a response to the phrase.");
Could that be a little more descriptive, maybe actually ask the phrase?
Hope that hint helps. Let me know if it doesn't.

15,730 PointsThis is really close. One thing it is looking for, in promptForWord, it wants to know which phrase. You can replace
System.out.println("Please insert a word as a response to the phrase.");
with
System.out.printf("%s: ", phrase);
