    Unhappy Help with Beginner JAVA method!

    Hi guys I can't seem to get this method working. Any help is appreciated on what's wrong in my code thanks!

    public static final String SENTENCE_SEPARATORS = "[.?!]";
         * Given an ArrayList of lines from a text file, create a new array list
         * in which each entry is a sentence from the file 
         * with SENTENCE_SEPARATORS removed but no other changes.
         * A sentence is defined to be a sequence of characters that 
         * (1) is terminated by (but doesn't include) the characters ! ? . or the end of the file, 
         * (2) excludes whitespace on either end, and 
         * (3) is not empty.
        public static ArrayList<String> convertFileLinesToSentences(ArrayList<String> filelines)
            String allLines = "";
            for(String lines : filelines) { // add all lines into a single string
                allLines = (lines + " ");
            String[] sentencesArray = allLines.split(SENTENCE_SEPARATORS);  // split at sentence separators
            ArrayList<String> entries = new ArrayList<>(Arrays.asList(sentencesArray)); // add sentences from array into ArrayList
            for(String sentence : entries) { // remove the sentence separators
                sentence.trim().replaceAll(SENTENCE_SEPARATORS, "");
            return entries;

    Neither do we. Can you provide more details such as copy and paste the exact error message (if you get one) or describe the behaviour and what it should do instead.
