Help me please ! I Have a windows machine, and when i try to compile my TreeStory version project i get an error like that.
Error:(27, 26) java: method readAllLines in class java.nio.file.Files cannot be applied to given types; required: java.nio.file.Path,java.nio.charset.Charset found: java.nio.file.Path reason: actual and formal argument lists differ in length
// After you've completed the TODOs locally paste Main.java here
// After you've completed the TODOs locally paste Prompter.java here
# 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

Full Stack JavaScript Techdegree Graduate 50,856 PointsAs the compiler message says: "The argument lists differ in length".
The 'Files.readAllLines' method accepts two arguments. You are giving it only a 'Path' object, you also need to pass in the charset to use for decoding.
Like this:
java.nio.file.Files.readAllLines(path, Charsets.UTF_8);
