OffsetDateTimeDemo.java

import java.time.OffsetDateTime;
import java.time.ZoneOffset;

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);
        /*
         * Parameters:
         *
         * dayOfYear - the day-of-year to set in the result, from 1 to
         * 365-366
         *
         * Returns:an OffsetDateTime based on this date with the
         * requested day, not null
         */
        OffsetDateTime offsetDateTime2 = offsetDateTime1.withDayOfYear(150);
        System.out.println("DayOfYear changed     = " + offsetDateTime2);

        /*
         * Parameters:
         *
         * offset - the zone offset to change to, not null
         *
         * Returns:an OffsetDateTime based on this date-time with the
         * requested offset, not null
         */
        OffsetDateTime offsetDateTime3 = offsetDateTime2
                .withOffsetSameInstant(ZoneOffset.UTC);
        System.out.println("Offset changed        = " + offsetDateTime3);
    }

}

Output

offsetDateTime1       = 2017-02-03T10:15:30+01:00
DayOfYear changed     = 2017-05-30T10:15:30+01:00
Offset changed        = 2017-05-30T09:15:30Z
