Java Calculate Number of Weeks Between two ZonedDateTime

import java.time.ZonedDateTime;
import java.time.temporal.ChronoUnit;

public class WeeksBetweenZonedDateTimeExample {
    public static void main(String... args) {
        ZonedDateTime startZonedDateTime = ZonedDateTime.parse("2022-01-01T08:15:30+10:00[Australia/Sydney]");

        // Calculate Number of Weeks Between two ZonedDateTime
        long numberOfWeeks = ChronoUnit.WEEKS.between(startZonedDateTime, endZonedDateTime);

        System.out.println(String.format("Number of weeks between %s and %s is %d",

Number of weeks between 2022-01-01T09:15:30+11:00[Australia/Sydney] and 2022-02-01T09:15:30+11:00[Australia/Sydney] is 4
