The plusDays() method of OffsetDateTime class in Java returns a copy of this OffsetDateTime with the specified number of days added to the parsed date and time.
Syntax:
public OffsetDateTime plusDays(long days)
Parameter: This method accepts a single parameter days which specifies the days to be added to the parsed date. It can be negative also, in that case, it subtracts the number of days to it.
Return Value: It returns an OffsetDateTime based on this date-time with the days added and not null.
Exceptions: The program throws a DateTimeException when it exceeds the supported data and time range.
Below programs illustrate the plusDays() method:
Program 1:
// Java program to demonstrate the plusDays() 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 days System.out.println( "Date1 after adding days: " + date1.plusDays(- 120 )); } } |
Date1: 2018-12-12T13:30:30+05:00 Date1 after adding days: 2018-08-14T13:30:30+05:00
Program 2 :
// Java program to demonstrate the plusDays() 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 days System.out.println( "Date1 after adding days: " + date1.plusDays( 140 )); } } |
Date1: 2018-12-12T13:30:30+05:00 Date1 after adding days: 2019-05-01T13:30:30+05:00
