OffsetDateTimeDemo.java

import java.time.OffsetDateTime;

public class OffsetDateTimeDemo

{

    public static void main(String[] args)

    {

        OffsetDateTime offsetDateTime1 = OffsetDateTime.parse("2017-02-03T10:15:30+01:00");

        System.out.println("offsetDateTime1       = "+offsetDateTime1);

        OffsetDateTime offsetDateTime2 = offsetDateTime1.withYear(2018);

        System.out.println("\nYear changed          = "+offsetDateTime2);

        OffsetDateTime offsetDateTime3 = offsetDateTime2.withMonth(10);

        System.out.println("Month changed         = "+offsetDateTime3);

        OffsetDateTime offsetDateTime4 = offsetDateTime3.withDayOfMonth(25);

        System.out.println("Day changed           = "+offsetDateTime4);

        OffsetDateTime offsetDateTime5 = offsetDateTime4.withHour(1);

        System.out.println("Hour changed          = "+offsetDateTime5);

        OffsetDateTime offsetDateTime6 = offsetDateTime5.withMinute(10);

        System.out.println("Min changed           = "+offsetDateTime6);

        OffsetDateTime offsetDateTime7 = offsetDateTime6.withSecond(20);

        System.out.println("Sec changed           = "+offsetDateTime7);

        OffsetDateTime offsetDateTime8 = offsetDateTime7.withNano(50);

        System.out.println("NanoSec changed       = "+offsetDateTime8);

    }

}

Output

offsetDateTime1       = 2017-02-03T10:15:30+01:00

Year changed          = 2018-02-03T10:15:30+01:00

Hour changed          = 2018-10-25T01:15:30+01:00

Min changed           = 2018-10-25T01:10:30+01:00

Sec changed           = 2018-10-25T01:10:20+01:00

NanoSec changed       = 2018-10-25T01:10:20.000000050+01:00
