// of minusWeeks(long weeks_val) method 
// of LocalDate

import java.time.*;

public class MinusWeeksOfLocalDate {
    public static void main(String args[]) {
        long weeks = 3;
        // Instantiates two LocalDate
        LocalDate l_da1 = LocalDate.parse("2007-04-04");
        LocalDate l_da2 = LocalDate.of(2008, Month.FEBRUARY, 06);

        // Display l_da1,l_da2 and weeks
        System.out.println("LocalDate l_da1, l_da2: ");
        System.out.println("l_da1: " + l_da1);
        System.out.println("l_da2: " + l_da2);
        System.out.println("weeks to subtract: " + weeks);

        System.out.println();

        // Here, this method subtracts the
        // given weeks from this date l_da1
        // i.e. here we are subtracting 3
        // weeks from the date l_da1
        LocalDate minus_weeks = l_da1.minusWeeks(weeks);

        // Display minus_weeks
        System.out.println("l_da1.minusWeeks(weeks): " + minus_weeks);

        // Here, this method subtracts the 
        // given weeks from this date l_da2
        // i.e. here we are subtracting 3
        // weeks from the date l_da2
        minus_weeks = l_da2.minusWeeks(weeks);

        // Display minus_weeks
        System.out.println("l_da2.minusWeeks(weeks): " + minus_weeks);
    }
}

Output

LocalDate l_da1, l_da2: 
l_da1: 2007-04-04
l_da2: 2008-02-06
weeks to subtract: 3

l_da1.minusWeeks(weeks): 2007-03-14
l_da2.minusWeeks(weeks): 2008-01-16
