The plusWeeks() method of LocalDate class in Java is used to add the number of specified week in this LocalDate and return a copy of LocalDate.For example, 2018-12-24 plus one week would result in 2018-12-31. This instance is immutable and unaffected by this method call.
Syntax:
public LocalDate plusWeeks(long weeksToAdd)
Parameters: This method accepts a single parameter weeksToAdd which represents the weeks to add, may be negative.
Return value: This method returns a LocalDate based on this date with the weeks added, not null.
Exception: This method throws DateTimeException if the result exceeds the supported date range.
Below programs illustrate the plusWeeks() method:
Program 1:
// Java program to demonstrate// LocalDate.plusWeeks() method  import java.time.*;  public class GFG {    public static void main(String[] args)    {          // create a LocalDate object        LocalDate date            = LocalDate.parse("2018-12-26");          // print instance        System.out.println("LocalDate before"                           + " adding weeks: " + date);          // add 5 weeks        LocalDate returnvalue            = date.plusWeeks(5);          // print result        System.out.println("LocalDate after "                           + " adding weeks: " + returnvalue);    }} |
Output:
LocalDate before adding weeks: 2018-12-26 LocalDate after adding weeks: 2019-01-30
