OffsetDateTime plusWeeks() method in Java with examples
  • Last Updated : 17 Dec, 2018

The plusWeeks() method of OffsetDateTime class in Java returns a copy of this OffsetDateTime with the specified number of weeks added to the parsed date and time.

Syntax:

public OffsetDateTime plusWeeks(long weeks)

Parameter: This method accepts a single parameter weeks which specifies the weeks to be added to the parsed date. It can be negative also, in that case, it subtracts the number of weeks to it.

Return Value: It returns an OffsetDateTime based on this date-time with the weeks added and not null.

Exceptions: The program throws a DateTimeException when it exceeds the supported data and time range.



Below programs illustrate the plusWeeks() method:

Program 1:




// Java program to demonstrate the plusWeeks() method
  
import java.time.OffsetDateTime;
import java.time.ZonedDateTime;
  
public class GFG {
    public static void main(String[] args)
    {
  
        // Parses the date1
        OffsetDateTime date1
            = OffsetDateTime
                  .parse(
                      "2018-12-12T13:30:30+05:00");
  
        // Prints dates
        System.out.println("Date1: " + date1);
  
        // Subtracts the number of weeks
        System.out.println("Date1 after adding weeks: "
                           + date1.plusWeeks(-120));
    }
}
Output:
Date1: 2018-12-12T13:30:30+05:00
Date1 after adding weeks: 2016-08-24T13:30:30+05:00

Program 2 :




// Java program to demonstrate the plusWeeks() method
  
import java.time.OffsetDateTime;
import java.time.ZonedDateTime;
  
public class GFG {
    public static void main(String[] args)
    {
  
        // Parses the date1
        OffsetDateTime date1
            = OffsetDateTime
                  .parse(
                      "2018-12-12T13:30:30+05:00");
  
        // Prints dates
        System.out.println("Date1: " + date1);
  
        // Subtracts the number of weeks
        System.out.println("Date1 after adding weeks: "
                           + date1.plusWeeks(140));
    }
}
Output:
Date1: 2018-12-12T13:30:30+05:00
Date1 after adding weeks: 2021-08-18T13:30:30+05:00
