Pattern pattern = Pattern.compile("([0-2][0-9])\\:([0-6][0-9])\\:([0-6][0-9])");
Matcher matcher = pattern.matcher("23:01:59");
matcher.matches(); //这一步必须有 否则报错    
String result1 = matcher.group(1);
    String result2 = matcher.group(2);
    String result3 = matcher.group(3);
    System.out.println(result1 + " " + result2 + " " + result3 + " ");

测试里碰上一29:69:69的时间怎么办?
