This is the error I am receiving: "Did you prompt the user for the story (1)? I didn't see the first double underscored word prompted (2)."

Java Web Development Techdegree Graduate 22,175 PointsTwo things:
1. Don't print censored word when you censor it, otherwise Craig tests consider you failing in censoring:
// fails
// System.out.printf("%s is censored. Please enter another placeholder: ", word);
// should pass
System.out.println("word is censored. Please enter another word ");
2. You have to print placeholder, i.e. Please enter __name__, and not just Please enter placeholder
// System.out.printf("Enter the placeholder: ");
System.out.printf("Enter the %s: ", phrase);

8,041 PointsWhy does the code crash if I don't include in the promptForWord method :
word = mReader.readLine();
public String promptForWord(String phrase) throws IOException {
System.out.printf("Enter the %s: ", phrase);
String word = mReader.readLine();
while (mCensoredWords.contains(word)) {
System.out.println("word is censored. Please enter another word ");
word = mReader.readLine();
}
return word;

Front End Web Development Techdegree Student 14,334 PointsThank you for posting this! I originally had an issue with getting it to pass because I was printing "Enter the response: " rather than using a printf statement, which actually works very well since it loads in the type of response you should be giving.
