java判断现在时间是否是某个日期的几天后

Date dendtime = team.getDenddate();
//获取两天后的日期
Calendar calendar = Calendar.getInstance();
calendar.setTime(dendtime);
calendar.set(Calendar.DATE, calendar.get(Calendar.DATE) + 2);
Date time = calendar.getTime();

//对比大小
if(time.getTime() > Calendar.getInstance().getTime().getTime()){
map.put("success", false);
map.put("message", "不在两天后！！！");
return map;
}
