    Hello Alysosh,

    Welcome to the Java Programming Forums

    I'm unsure what you mean by returning the whitespace between the tokens?

    can you not do something like this,
    Scanner s = new Scanner(new FileReader("test.java")); // handle exceptions
    while(s.hasNext()){
      s.readLine(); // do something with this value...like search it for words etc
    }
    that way you know that the only white space you are skipping is equal to
    System.getProperty("line.separator")
    and ill not be skipping tabs, spaces etc

    Regards,
    Chris

    Yeah thats what I was going to suggest Chris. You can read it in line by line and write it out in exactly the same way in the same format.
