Below programs illustrate the LocalDateTime.plusWeeks() method in Java:
Program 1:
Java
// Program to illustrate the plusWeeks() methodimport java.util.*;import java.time.*;public class GfG { public static void main(String[] args) { LocalDateTime dt1 = LocalDateTime .parse("2018-01-11T10:15:30"); System.out.println("LocalDateTime with 15 weeks added: " + dt1.plusWeeks(15)); }} |
Output:
LocalDateTime with 15 weeks added: 2018-04-26T10:15:30
Program 2:
Java
// Program to illustrate the plusWeeks() methodimport java.util.*;import java.time.*;public class GfG { public static void main(String[] args) { LocalDateTime dt1 = LocalDateTime .parse("2018-01-11T08:15:30"); System.out.println("LocalDateTime with -2 weeks added: " + dt1.plusWeeks(-2)); }} |
Output:
