How to make "this, string format" into two tokens ("this" and "string format")

Question

Im reading in a file and each line is as follows

Derek Simons, Jason baker
Jack Smith, Rob Thomson

The problem is with my tokenizer

StringTokenizer st = new StringTokenizer(line, ",");
    while(st.hasMoreTokens()){ 
       System.out.println(st.nextToken());
    }

the output is

Derek Simons
 Jason baker
Jack Smith
 Rob Thomson

how can I get rid of that extra blank space? so that the output would be

Derek Simons
Jason baker
Jack Smith
Rob Thomson

Any help is appreciated thanks!

What did you try so far to figure this out? Google? String javadoc maybe? — samitgaur, Feb 15 '11 at 07:29

I don't know which programming language you are using, but in many languages there is something called Trim(). so you do s.Trim();, where s is the string. That will remove all blanks

Yeah try: System.out.println(st.nextToken().trim()); – muddybruin Feb 15 '11 at 07:20

You can avoid having to trim each string manually if the input is always in the form you describe:

String[] tokens = line.split(",\\s*")

Now tokens will contain each name without leading spaces in the second token.

Did you consider using the .trim method?

Returns a copy of the string, with leading and trailing whitespace omitted.

You could use trim() or even just specify you StringTokenizer's delimiter as ", " (a comma followed by a space) instead of just ",".
