// WeekFields.weekOfMonth() method 

import java.time.DayOfWeek; 

import java.time.LocalDate; 

import java.time.temporal.TemporalField; 

import java.time.temporal.WeekFields; 

public class GFG { 

    public static void main(String[] args) 

    { 

        // create WeekFields 

        WeekFields weekFields 

            = WeekFields.of(DayOfWeek.MONDAY, 1); 

        // apply weekOfMonth() 

        TemporalField weekOfMonth 

            = weekFields.weekOfMonth(); 

        // create a LocalDate 

        LocalDate day 

            = LocalDate.of(2021, 12, 21); 

        // get week of month for localdate 

        int wom = day.get(weekOfMonth);
