What I am doing wrong? 1. I append all the file content to a string builder. 2. I replace all the spaces of the builder.toString with a punctuation. 3. I split the string using the "\\p{Punct}" regex into an aray. 4. I compare all the resulting string with the "world" and increment when I have a match. Can't pass the final task. It says: Determine why the program didn't find all instances of the word "world" in the file.
