Getting more than one result from regex groups

Question

Thanks to everyone in advance -
I cannot seem to figure out why I wouldnt receive multiple groups back from this match. I would assume I would receive:
[hello]
[john]
instead i am getting:
[hello]
[hello]
It seems like the regex stops after the first match is found, which leads me to believe that it has to do with some sort of flag -
     String Format = "[hello] my name is [sam]";
          String RegexPattern = "(\\[.*?\\])";
          Pattern MyPattern = Pattern.compile(RegexPattern, Pattern.CASE_INSENSITIVE | Pattern.DOTALL );
          Matcher MyMatcher = MyPattern.matcher(Format);
          if(MyMatcher.find()) {
               for(int i = 0; i <= MyMatcher.groupCount(); i++) {
                    out.print(MyMatcher.group(i) +"<br>");
          }Thanks,
Sam

Groups are a static concept. You only have one group.
while(MyMatcher.find()) {
    out.print(MyMatcher.group(1) +"<br>");
}
