java 隨機數,剩餘數

Calendar cal = Calendar.getInstance(); // int year = cal.get(Calendar.YEAR);// 獲取年份 int month = cal.get(Calendar.MONTH);// 獲取月份 int day = cal.get(Calendar.DATE);// 獲取日 int hour = cal.get(Calendar.HOUR);// 小時 // int minute = cal.get(Calendar.MINUTE);// 分 // int second = cal.get(Calendar.SECOND);// 秒 int DAY_OF_WEEK = cal.get(Calendar.DAY_OF_WEEK);// 一週的第幾天 int customNumber = day + month; customNumber += hour * 6 + DAY_OF_WEEK; //若是超過195 if (customNumber>195) { customNumber=196; }

效果圖 今天申請多少人 還剩餘多少人

public String wholeHouseCustom(ModelMap modelMap, HttpServletRequest req, HttpServletResponse res, Integer pageSize) {
	Calendar cal = Calendar.getInstance();
	// int year = cal.get(Calendar.YEAR);// 獲取年份
	int month = cal.get(Calendar.MONTH);// 獲取月份
	int day = cal.get(Calendar.DATE);// 獲取日
	int hour = cal.get(Calendar.HOUR_OF_DAY);// 小時
	int minute = cal.get(Calendar.MINUTE);// 分
	// int second = cal.get(Calendar.SECOND);// 秒
	int DAY_OF_WEEK = cal.get(Calendar.DAY_OF_WEEK);// 一週的第幾天
	int customNumber = day + month;
	customNumber += hour * 6 + DAY_OF_WEEK+minute/10;
	//若是超過195
	if (customNumber>195) {
		customNumber=196;
	}
	modelMap.addAttribute("customNumber", customNumber);
	modelMap.addAttribute("leaveNumber", 200 - customNumber);
	return "/public/custom/custom";
}

小時 須要從新設置
