如何在java.util.Date中获取当前季度的第一个日期和最后一个日期

private static Date getFirstDayOfQuarter(Date date) {    Calendar cal = Calendar.getInstance();    cal.setTime(date);    cal.set(Calendar.DAY_OF_MONTH, 1);    cal.set(Calendar.MONTH, cal.get(Calendar.MONTH)/3 * 3);    return cal.getTime();}private static Date getLastDayOfQuarter(Date date) {    Calendar cal = Calendar.getInstance();    cal.setTime(date);    cal.set(Calendar.DAY_OF_MONTH, 1);    cal.set(Calendar.MONTH, cal.get(Calendar.MONTH)/3 * 3 + 2);    cal.set(Calendar.DAY_OF_MONTH, cal.getActualMaximum(Calendar.DAY_OF_MONTH));    return cal.getTime();}

这应该可以，但是我建议您比我更仔细地测试它。注意：Java中int值的除法返回下限值。
