Hello there. I've been trying to solve this challenge for a bit now and after completing the TO-DOs (My"solution" is probably wrong so let me know) but i keep getting this error:
Couldn't load censored words

It seems like the code cannot read the file.However the censored_words.txt is there and it does contain the four words.I can't seem to figure this problem out.Any ideas?Below you will find my code:
MAIN:

import java.util.Arrays;
import java.util.List;
public class Main {
public static void main(String[] args) {
// write your code here
Prompter prompter = new Prompter();

Template tmpl = new Template(story);
prompter.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
