String x = "20161111"; System.out.println(x.replaceAll("(\\d{4})(\\d{2})(\\d{2})", "$1-$2-$3"));
String date = "20161011"; Date format = new SimpleDateFormat("yyyyMMdd").parse(date); String dd = new SimpleDateFormat("yyyy-MM-dd").format(format); System.out.println(dd);
String x = "20161111";System.out.println(x.replaceAll("(\d{4})(\d{2})(\d{2})", "$1-$2-$3"));
