计算同一天内，两个时间之间的分钟数

计算同一天内，两个时间之间的分钟数:

/** * <pre> * 计算同一天内，两个时间之间的分钟数 * </pre> *  * @param date1   时间1 * @param date2   时间2 * @return betweenMinutes 两个时间的间隔分钟数 */public static int getBetweenMinutes(Date date1, Date date2) {if (date1 == null || date2 == null) {return -1;}int betweenMinutes; //两个时间间隔分钟数int betweenHours; //两个时间间隔小时数Calendar c1 = Calendar.getInstance();Calendar c2 = Calendar.getInstance();c1.setTime(date1);c2.setTime(date2);if (c1.after(c2)) { //确保第二个时间一定大于第一个时间c2.setTime(date1);c1.setTime(date2);}betweenHours = c2.get(Calendar.HOUR_OF_DAY)- c1.get(Calendar.HOUR_OF_DAY);betweenMinutes = c2.get(Calendar.MINUTE) - c1.get(Calendar.MINUTE);betweenMinutes += betweenHours * 60;return betweenMinutes;}
