比较忽略毫秒的日期？ [英] Compare dates ignoring milliseconds?

问题描述

有没有办法比较两个日历对象，但忽略毫秒？

我编写了一个比较两个日历对象的测试用例， 但有个问题。虽然所有日，月，分和小时都匹配，但毫秒不匹配。我在获得实际日期之前得到预期日期：

I have written a test case that compared two calendar objects, but there is a problem. Although all of the day, month, minutes and hours match, the milliseconds doesn't matches. I get the expected date before getting the real date:

/**
 * @return
 */
private Calendar getExpectedOneMonthDateFromCurrentDate() {
    Calendar expectedOneMonth = Calendar.getInstance();
    expectedOneMonth.add(Calendar.MONTH, -1);
    return expectedOneMonth;
}

assertEquals(getExpectedOneMonthDateFromCurrentDate(),
             DateRange.LAST_ONE_MONTH.getToDate());

推荐答案

从日历中删除毫秒

cal.set(Calendar.MILLISECOND, 0);
