Not sure what I am messing up here, but I keep on getting "Bummer! Looks like you didn't present the TreeStory (3)" for the last challenge of the Local Development Environments stream. Am I missing something in my code?
Main.java: package com.teamtreehouse;

public static void main(String[] args) {
// write your code here

String story = null;
try {
story = prompter.promptForTemplate();
} catch (IOException ioe) {
ioe.printStackTrace();
System.exit(0);
}
Template tmpl = new Template(story);
prompter.run(tmpl);
}
}

Java Web Development Techdegree Graduate 22,175 PointsThe error was very hard to find, but I think I did it. The problem is, when you prompt user for response in promptForWord method, use change his response to be trimmed and lowercased. When Craigs tests checking you TreeStory they don't match. Do you see the problem. Try to change your promptForWord method to this one:
public String promptForWord(String phrase) throws IOException {
String response = "";
System.out.printf("Please provide a %s: ", phrase);
// response = mReader.readLine().toLowerCase().trim(); // wrong
response = mReader.readLine(); // correct
while(mCensoredWords.contains(response)) {
System.out.printf("Please be nice! Try again.%n");
System.out.printf("Please provide a %s: ", phrase);
// response = mReader.readLine().toLowerCase().trim(); // wrong
response = mReader.readLine(); // correct
}
return response;
}
One more advice though: When you have problems with the challenge. Try to push button 'Get Help'. It won't work after you pushed 'Check' and have errors - it is a bug in treehouse. But If you just put your code and then before compiling press Get Help, it should automatically include your code to question in community.
Otherwise try to use preview button and take a look at your response before you send it (Take a look at Markdown cheatsheet hint).
You know: the easier to check your error: copy/paste code, the faster people will help you. And also feel free to edit your post. If you posted it late at night, and no one answered feel free to comeback next day and format it properly. Even on StackOverflow people edit their posts :)

5,033 Pointshello friends. Looks like you didn't present the TreeStory (3) is the error that Iam geting when I submit my code. I dont have any errors in InteliJ. this is the code:

try {

Test number three check that your treestory is properly printed. Method printing your treestory is:
public void run(Template tmpl) {
List<String> results = null;
try {
results = promptForWords(tmpl);
} catch (IOException e) {
System.out.println("There was a problem prompting for words");
e.printStackTrace();
System.exit(0);
}
// change this method. the error is very easy. Hint take a look how Craig prints treestory. in the given files
// the way you do it is incorrect.
// for (String s : results){
// System.out.print(s + "");
//}
}
