如何检查一天是在Java的当前周？

import java.time.LocalDate;
import java.time.ZoneId;
import java.util.Calendar;
import java.util.Date;

public class CurrentWeekChecker {
    public static void main(String[] args) {
        System.out.println("当前日期：" + LocalDate.now().toString());
        System.out.println("当前周：" + getWeekNumber(LocalDate.now()));
    }

    public static int getWeekNumber(LocalDate date) {
        ZoneId zoneId = ZoneId.systemDefault();
        Calendar cal = Calendar.getInstance(zoneId);
        cal.setFirstDayOfWeek(Calendar.MONDAY);
        cal.setMinimalDaysInFirstWeek(4);
        cal.set(Calendar.DAY_OF_WEEK, Calendar.MONDAY);
        cal.set(Calendar.WEEK_OF_YEAR, 1);
        Date weekStart = cal.getTime();
        Date now = new Date();
        long diffInMillies = (now.getTime() - weekStart.getTime()) / (1000 * 60 * 60 * 24);
        int weekNumber = (int) Math.ceil(diffInMillies / (7 * 24 * 60 * 60));
        return weekNumber;
    }
}

LocalDate date = LocalDate.of(2022, 1, 1);
int weekNumber = getWeekNumber(date);
System.out.println("2022年1月1日（星期一）在当年的周数是：" + weekNumber);
