    Cool Scanner delimiter


    I have an assignment and i think the authors made a mistake because the scanner useDelimiter() method is not working

    Here is the delimiter

    So far Ive coded

    Scanner scan = new Scanner(aFileName); // aFileName is an argument in the method header
    While (scan.hasNext())
    String aWord = scan.next()
    ... //add aWord to a hashMap for processing

    My question is what does the code in the delimiter mean? and can it detect commas i.e (,) or full stops for that matter

    Default Re: Scanner delimiter

    The code is using a regular expression. Go to the Pattern class in the Java API or google "regex tutorial" for more information.
