Hey there!

I am pretty new to this myself, and thanks for adding code tags... to tell you the truth though, I probably could have helped you if the entire code was posted; not savvy enough to tell what you need to do with just that bit of code. Let's have a look at the whole code..

Rest assured, I'll yell for help for you if I cannot see what you're asking, what I know is peanuts compared to a lot of our folks here, so you're in good hands. Add code in and see what happens.

In a bit!

By default, ! is an ordinary character, not a word character, so setting it to ordinary char doesn't change anything. Demo:

Expand|Select|Wrap|Line Numbers

 import java.io.*;
 
public class StreamTokenizerExample {

    public static void main(String[] args) throws IOException {

        String data = "abc! def";

        test(data, false);

        test(data, true);

    }
 
    static void test(String data, boolean setOrdinaryChar) throws IOException {

        StreamTokenizer s = new StreamTokenizer(new StringReader(data));

        if (setOrdinaryChar) s.ordinaryChar('!');
 
        for(int token; (token = s.nextToken()) != StreamTokenizer.TT_EOF; ) {

            String output = "??";

            if (token == StreamTokenizer.TT_WORD) {

                output = s.sval;

            } else if (token == StreamTokenizer.TT_NUMBER) {

                output = String.valueOf(s.nval);

            } else if (token == StreamTokenizer.TT_EOL) {

                output = "EOL";

            } else {

                output = String.valueOf((char)token);

            }

            System.out.println(output);

        }

        System.out.println();

    }

}
