Example:

// Java program to demonstrate the example 
// of plusWeeks(long weeks_val) method of LocalDate

import java.time.*;

public class PlusWeeksOfLocalDate {
    public static void main(String args[]) {
        long weeks = 4;
        // 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 add: " + weeks);

        System.out.println();

        // Here, this method adds the
        // given weeks to this date l_da1
        // i.e. here we are adding 4
        // weeks to the date l_da1
        LocalDate plus_weeks = l_da1.plusWeeks(weeks);

        // Display plus_weeks
        System.out.println("l_da1.plusWeeks(weeks): " + plus_weeks);

        // Here, this method adds the
        // given weeks to this date l_da2
        // i.e. here we are adding 4
        // weeks to the date l_da2
        plus_weeks = l_da2.plusWeeks(weeks);

        // Display plus_weeks
        System.out.println("l_da2.plusWeeks(weeks): " + plus_weeks);
    }
}

Output

LocalDate l_da1,l_da2 : 
l_da1: 2007-04-04
l_da2: 2008-02-06
weeks to add: 4

l_da1.plusWeeks(weeks): 2007-05-02
l_da2.plusWeeks(weeks): 2008-03-05
