Util.regex matcher.groupCount()

Question

Hello all. I am trying to parse some text using regex. What I am parsing may have 1 or more matches per line and I need access to each match independantly. The code shown below works well in finding all matches except for the m.groupCount() always returns 0. Thus I can't to anything with individual matches. How can get the groupCount() to function properly?
Thanks in advance.
f (currentLine.startsWith("LOCUSLINK")){
                  line++;
                  String pattern = "[0-9]+";
                  Pattern p = Pattern.compile(pattern, Pattern.CASE_INSENSITIVE);
                  Matcher m = p.matcher(currentLine);
                  while(m.find()) {
                    int count = m.groupCount();
                    for (int x = 0; x <= m.groupCount(); x++)
                    System.out.println(line+"="+x+"="+count);

There aren't capturing groups and really don't need to use in this case.
Try this simple way:
String re = "\\d+";
Matcher m = Pattern.compile(re).matcher(anyString);
for (int j=1; m.find(); j++) {
System.out.println("matching " + j + ": " + m.group(0));
