Front End Web Development Techdegree Student 24,429 PointsMy code running well in IntelliJ IDEA, but fails in the test... What's wrong?
It seems that the readLine() method reads 2 inputs first and then at the end there is a null input... How can I fix it?

# This is essentially what I am testing
1. The user is prompted for a string template (the one with the double underscores in it)
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 TeacherMake sure you prompt for the story and not use the provided one. See step #1.
Did you get it solved?

Front End Web Development Techdegree Student 24,429 PointsYes I have the Template class too... It was a simple bug or missing info in the bug report of this course tester, I have finally corrected and finished the course for the 4th run, but done! :D

Front End Web Development Techdegree Student 24,429 PointsYes! Solved. The error message was little missleading for that... But problem solved.
