/**
 * Get a diff between two dates
 *
 * @param oldDate
 *            the old date
 * @param newDate
 *            the new date
 * @return the diff value, in the days
 */
public static long getDateDiff(SimpleDateFormat format, String oldDate, String newDate) {
	try {
		return TimeUnit.DAYS.convert(
			format.parse(newDate).getTime() - format.parse(oldDate).getTime(),
			TimeUnit.MILLISECONDS);
	} catch (Exception e) {
		e.printStackTrace();
		return 0;
	}
}

使用方式：

SimpleDateFormat sdf = new SimpleDateFormat("dd/MM/yyyy");
long dateDiff = getDateDiff(sdf, "4/12/2017", "6/12/2017");
System.out.println(" days diff is : " + dateDiff);

控制台将输出:

1
days diff is : 2
