    Default Help me understand Delimiter limitations?

    I'm trying to scan a string from a file that has int, words and double numbers. I want to just print the words, how do I ignore the double type numbers in the file? I was thinking this would work...

    Scanner scanner = new Scanner(line);
    scanner.useDelimiter(double);
    System.out.print(scanner.next() + " ");

    Delimiter doesn't like it when I don't have " " and a character with it.

    There are 2 useDelimiter methods. One takes a Pattern as a parameter the other takes a String as a parameter. The reserved word 'double' is neither of those.

    So can you use a delimiter to skip passed Doubles?

    Did you read my above post? One of the methods takes a Pattern as a parameter. Do you know about the Pattern class? If not, did you look in the API for information about that class. Did you do a Google search for examples?

    A simple no would have sufficed Junky. You made me realize the importance of attitude and communication in the business world though. Even though I'm new at programming and still getting my feet wet, employer's want people who can understand one another. You did not demonstrate understanding of the fundamentals of my problem here. I asked a simple question, obviously you pointed out that you can not use double syntax with delimiter. However, instead of leading me down a dark tunnel, you could have lead me to another avenue to a solution. I'm glad I suck at programming and not with people skills. Problem solved.

    My post was aimed at you finding the answer for yourself instead of relying on someone spoonfeeding you the answer. As far as I am concerned those that refuse to do any research themselves and just wait for fully coded solutions suck period!
