Java question

Im trying to use the useDelimiter() function to break up data where there are commas, but when i output the data it works, but it outputs the comma. :S

myFile is my scanner object.

myFile.useDelimiter("\\s*,\\s*");

Is there another way to write this statement without the comma being saved?

Scanner doesn't do that for me. Maybe you are outputing commas when you print? For instance Lists print commas between their elements.

Code:

import java.util.Scanner;
public class Delim {
    public static void main(String[] args) {
        Scanner scan = new Scanner("foo, bar, blah , as , ,,saf afa,");
        scan.useDelimiter("\\s*,\\s*");
        while(scan.hasNext())
            System.out.println(scan.next());
    }
}

That code gives me output:

Code:

~/src/java% java Delim                                                         
foo
bar
blah
as


saf afa

No commas here...

you can also use the StringTokenizer Class. It works the similar way.
