String을 날짜 포맷으로 변환하기!

String을 날짜 포맷으로 변환하기!

regTime : 20150522141253

reqTime : 20150428234211

위와 같은 String형식을..

2개의 format을 선언 한 뒤

DateFormat formatter = new SimpleDateFormat("yyyyMMddHHmmss"); SimpleDateFormat sdf = new SimpleDateFormat("yyyy/MM/dd HH:mm:ss");

아래처럼 작업을 해주면 됩니다.

try { outputMap.put("작업일", sdf.format(formatter.parse(regTime))); outputMap.put("신청일", sdf.format(formatter.parse(reqTime))); } catch (ParseException e) { e.printStackTrace(); }

변환 과정

regTime : 20150522141253 reqTime : 20150428234211 regTime2 : Fri May 22 14:12:53 KST 2015 reqTime2 : Tue Apr 28 23:42:11 KST 2015 regTme3 : 2015/05/22 14:12:53 reqTime3 : 2015/04/28 23:42:11
