public static void main(String[] args) {
final PatternMatcher regex = new PatternMatcher("(\\d{2,4}-\\d{1,2}-\\d{1,2})");
if (regex.match("05-1-10,100;2005-01-11,1000")) {
String[][] matches = regex.getMatches();
for (int i = 0; i < matches.length; i++) {
for (int j = 0; j < matches[i].length; j++) {
System.out.println(matches[i][j]);
}
}
}
}
