Week numbers from start date to end date Java

I trying to get the week numbers which fall between a given start date and end date in Java. This is ISO8601 date.

Example 
startDate - "2018-08-24T12:18:06,166"
endDate -  "2019-08-24T11:18:06,166"

The current week number is 34.

For this example, I would get 34,35,36... Last week number of 2018..1,2...last week number of 2019 and so on

Is there a good solution to this ?

Presently I got it worked with same year date range, what I tried is, I get the start week number and end week number from the start date and end date, and then I loop it giving the start value and end value. But if the date range falls in multiple years, how would it be? Can any one help me

If you are using Java 8 you can use java.time API Like so :

int addWeek = 0;
if(startDate.get(WeekFields.ISO.weekOfYear()) < endDate.get(WeekFields.ISO.weekOfYear())){
    addWeek = 1;
}
long weeks = WEEKS.between(startDate, endDate) + addWeek;//Get the number of weeks in your case (52)
List<Integer> numberWeeks = new ArrayList<>();
if (weeks >= 0) {
    int week = 0;
    do {
        //Get the number of week
        int weekNumber = startDate.plusWeeks(week).get(WeekFields.ISO.weekOfYear());
        numberWeeks.add(weekNumber);
        week++;
    } while (week <= weeks);
}

[34, 35, 36, 37, 38, 39, 40, 41, 42, 43, 44, 45, 46, 47, 48, 49, 50, 51, 52,
  1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12, 13, 14, 15, 16, 17, 18, 19, 20, 21, 
 22, 23, 24, 25, 26, 27, 28, 29, 30, 31, 32, 33, 34]

Note that you get both week numbers from both years, weeks of 2018 [34-52], then weeks of 2019 [1-33]
