Question

I am having difficulties with a program that I have been working on all day. I am trying to read a text file and read each line one at a time. Take that line and make an arraylist of the words of the line. then using the index of the arraylist define terms with it.

public class PCB {

    public static void main(String arg[]) {
        read();
    }

    public static ArrayList read() {    
        BufferedReader inputStream = null;
        ArrayList<String> tokens = new ArrayList<String>();
        try {
            inputStream = new BufferedReader(new FileReader("processes1.txt"));

            String l;
            while ((l = inputStream.readLine()) != null) {
                Scanner tokenize = new Scanner(l);
                while (tokenize.hasNext()) {
                    tokens.add(tokenize.next());
                }
                return tokens;
            }
        } catch (IOException ioe) {
            ArrayList<String> nothing = new ArrayList<String>();
            nothing.add("error1");
            System.out.println("error");
            //return nothing;
        }
        return tokens;
    }
}

The error I am getting is it only reads the first line. What am I doing wrong?
Thank you so much in advance

You have “return tokens;” in your while loop. Seems like that early return would effectively cut off processing on the first line.
