Don't compare strings with ==, use equals() method. That's the main bug in your program. Or you might consider equalsIgnoreCase(), if you really want "b" to match "B".
Another bug is that you call nextToken() twice in a row, without checking hasMoreTokens() in between. If a line has only one token, you'll get an exception there, which I suspect is not what you want. [ January 23, 2008: Message edited by: Peter Chase ]

Just to be sure, you are aware that the javadoc of StringTokenizer contains the following sentence?
StringTokenizer is a legacy class that is retained for compatibility reasons although its use is discouraged in new code. It is recommended that anyone seeking this functionality use the split method of String or the java.util.regex package instead.
