java 随机数,剩余数

摘要: java 随机数,剩余数

Calendar cal = Calendar.getInstance();
// int year = cal.get(Calendar.YEAR);// 获取年份
int month = cal.get(Calendar.MONTH);// 获取月份
int day = cal.get(Calendar.DATE);// 获取日
int hour = cal.get(Calendar.HOUR);// 小时
// int minute = cal.get(Calendar.MINUTE);// 分
// int second = cal.get(Calendar.SECOND);// 秒
int DAY_OF_WEEK = cal.get(Calendar.DAY_OF_WEEK);// 一周的第几天
int customNumber = day + month;
customNumber += hour * 6 + DAY_OF_WEEK;
//如果超过195
if (customNumber>195) {
customNumber=196;
}

效果图 今天申请多少人 还剩余多少人

public String wholeHouseCustom(ModelMap modelMap, HttpServletRequest req, HttpServletResponse res, Integer pageSize) {
Calendar cal = Calendar.getInstance();
// int year = cal.get(Calendar.YEAR);// 获取年份
int month = cal.get(Calendar.MONTH);// 获取月份
int day = cal.get(Calendar.DATE);// 获取日
int hour = cal.get(Calendar.HOUR_OF_DAY);// 小时
int minute = cal.get(Calendar.MINUTE);// 分
// int second = cal.get(Calendar.SECOND);// 秒
int DAY_OF_WEEK = cal.get(Calendar.DAY_OF_WEEK);// 一周的第几天
int customNumber = day + month;
customNumber += hour * 6 + DAY_OF_WEEK+minute/10;
//如果超过195
if (customNumber>195) {
customNumber=196;
}
modelMap.addAttribute("customNumber", customNumber);
modelMap.addAttribute("leaveNumber", 200 - customNumber);
return "/public/custom/custom";
}

小时 需要重新设置
