Java Program to get the beginning and end date of the week
At first, set a date:
LocalDate date = LocalDate.of(2019, 4, 16);
Now, get the date for the beginning of the week:
LocalDate start = date; while (start.getDayOfWeek() != DayOfWeek.MONDAY) { start = start.minusDays(1); }
Now, get the date for the end of the week:
LocalDate end = date; while (end.getDayOfWeek() != DayOfWeek.SUNDAY) { end = end.plusDays(1); }
Example
import java.time.DayOfWeek; import java.time.LocalDate; public class Demo { public static void main(String[] argv) { LocalDate date = LocalDate.of(2019, 4, 16); System.out.println("Date = " + date); LocalDate start = date; while (start.getDayOfWeek() != DayOfWeek.MONDAY) { start = start.minusDays(1); } System.out.println("Start of the Week = " + start); LocalDate end = date; while (end.getDayOfWeek() != DayOfWeek.SUNDAY) { end = end.plusDays(1); } System.out.println("End of the Week = " + end); } }
Output
Date = 2019-04-16 Start of the Week = 2019-04-15 End of the Week = 2019-04-21
