获取当前时间

】第一种方式
DateFormat format=new SimpleDateFormat(“yyyy年MM月dd日”);
format.format(System.currentTimeMillis());

】第二种方式

    Calendar calendar=Calendar.getInstance();    calendar.get(Calendar.YEAR);    calendar.get(Calendar.MONTH);    calendar.get(Calendar.DAY_OF_MONTH);

将时间戳转化成时间

      SimpleDateFormat sdr = new SimpleDateFormat("yyyy年MM月dd日HH时mm分ss秒");          @SuppressWarnings("unused")          long lcc = Long.valueOf(wintime);          int i = Integer.parseInt(wintime);          String t1 = sdr.format(new Date(i * 1000L));
