The java.util.Date class implements the Comparable interface, so we can directly call the compareTo() method of Date to compare the size of the Date date type.
Syntax:
int compareTo(Date date)
Compares the Date object when this method is called with the specified date. When the two are equal, 0 is returned. If the calling object is before the specified date, a negative number is returned. The calling object returns a positive number after the specified date.
Specific code:

String beginTime = "2018-07-28 14:42:32"; String endTime = "2018-07-29 12:26:32"; SimpleDateFormat format = new SimpleDateFormat("yyyy-MM-dd HH:mm:ss"); try { Date date1 = format.parse(beginTime); Date date2 = format.parse(endTime); int compareTo = date1.compareTo(date2); System.out.println(compareTo); } catch (ParseException e) { e.printStackTrace(); }
The return value of the compareTo() method, date1 is less than date2 Returns -1, returns 1 if date1 is greater than date2, and returns 0 if they are equal.
