자바 날짜, 시간 구하기

* 현재 날짜와 시간, 분, 초 구하기

Calendar cld = Calendar.getInstance();
int cldYY = cld.get(Calendar.YEAR);
int cldMM = cld.get(Calendar.MONTH)+1;
int cldDD = cld.get(Calendar.DATE);
int cldHH_12 = cld.get(Calendar.HOUR);
int cldHH_24 = cld.get(Calendar.HOUR_OF_DAY);
int cldMIN = cld.get(Calendar.MINUTE);
int cldAM = cld.get(Calendar.AM);




* 24시, 12시 확인

boolean format_24 = DateFormat.is24HourFormat(this);
String todayDate = "";
String todayTime = "";
String todayAMPM = "";
mContext.getResources().getString(R.string.year);
todayAMPM = (cldAM!=0) ? "AM":"PM";
todayDate = cldYY+mContext.getResources().getString(R.string.year)+" "+cldMM+mContext.getResources().getString(R.string.month)+" "+cldDD+mContext.getResources().getString(R.string.day);
if(format_24){

todayTime = cldHH_24+mContext.getResources().getString(R.string.hour)+" "+cldMIN+mContext.getResources().getString(R.string.minute);
}else{
todayTime = todayAMPM+" "+cldHH_12+"시 "+cldMIN+"분";
}





* GregorianCalendar 을 사용하여 날, 시간을 세팅해서 msc로 값을 구하기

GregorianCalendar g = (GregorianCalendar) Calendar.getInstance();
g.set(reservDateValue_1, reservDateValue_2-1, reservDateValue_3, hour, reservTimeValue_3, 0);
sendTime = g.getTimeInMillis();
