java - 带有 Calendar.after 的 While 语句未启动

Question

所以我花了相当多的时间在谷歌上搜索并浏览了一些东西，但我就是无法让它发挥作用。即使 request.getEnd() 是在当前 startCal.getTime 之后几天，它也不会认为该语句为 true。有什么想法吗？

while(startCal.after(request.getEnd()))
            {
                /* Calculate new beginning */

                startCal.add(Calendar.DATE, 1);
                newBegin = startCal.getTime();
                System.out.println(newBegin);
                /* Calculate new ending */

                endCal.add(Calendar.DATE, 1);
                newEnd = endCal.getTime();

                /* Setting new dates and series ID */
                localRequest.setBegin(newBegin);
                localRequest.setEnd(newEnd);
                localRequest.setSeriesID(seriesID);

                /* Sending new reservation to database */
                //reserve(localRequest);
                System.out.println("RESERVATION DONE");
            }

Answer 1

even though the request.getEnd() is a couple days after the current startCal.getTime.

那么它无法启动也是有道理的!这行代码:

while(startCal.after(request.getEnd()))

表示“开始校准是在请求结束之后。”您所描述的数据恰恰相反!
