[Java] Get the dates of the past Monday and Sunday in order

Thing you want to do

If the acquisition target is the past 3 months This Week: Get the dates of the Monday and Sunday of the week that contains the current date Past Weeks: Get dates for each Monday and Sunday Last week: Get dates for Mondays and Sundays of the week containing dates 3 months ago


I received an indication from swordone and corrected the logic (6/25). * See comments

public static void main(String[] args) {

        //Get current date
        LocalDate now = LocalDate.now();

        //Get the date 3 months ago (change this date as appropriate, 3 months in this example)
        LocalDate targetDate = now.minusMonths(3);

        //Get the Monday of the current week
        LocalDate monday = now.with(DayOfWeek.MONDAY);

        //Get the Sunday of the current week
        LocalDate sunday = now.with(DayOfWeek.SUNDAY);

        int i = 0;
        while (!sunday.isBefore(targetDate)) {
            System.out.println(monday + " ~ " + sunday + " : " + (i == 0 ? "this week" : i + "Week ago"));
            monday = monday.minusDays(7);
            sunday = sunday.minusDays(7);

Execution result

The current date is 6/25. The acquisition target is up to 3 months in advance. I think it can be used when you want to specify the period for the past few weeks. Change the date to be acquired as appropriate and use it.
