public static void main(String[] args){
		try {
			//获取当前日期
			Date date = new Date();
			SimpleDateFormat sf = new SimpleDateFormat("yyyyMMdd");
			String nowDate = sf.format(date);
			System.out.println(nowDate);
			//通过日历获取下一天日期
			Calendar cal = Calendar.getInstance();
			cal.setTime(sf.parse(nowDate));
			cal.add(Calendar.DAY_OF_YEAR, +1);
			String nextDate_1 = sf.format(cal.getTime());
			System.out.println(nextDate_1);
			//通过秒获取下一天日期
			long time = (date.getTime() / 1000) + 60 * 60 * 24;//秒
			date.setTime(time * 1000);//毫秒
			String nextDate_2 = sf.format(date).toString();
			System.out.println(nextDate_2);
