List<SwhitechProcTopcover> dataList = getPcbMacList(vo);
		dataList.sort(new Comparator<SwhitechProcTopcover>() {
			@Override
			public int compare(SwhitechProcTopcover arg0, SwhitechProcTopcover arg1) {
				Date scanDe = arg0.getPcbMacScanDe();
				Date scanDe2 = arg1.getPcbMacScanDe();
				return scanDe.compareTo(scanDe2);//asc
				//return scanDe2.compareTo(scanDe);//desc
			}
		});

 

바로 override compare 재정의
