ZoneOffsetTransition of() method in Java with Example

Last Updated : 14 Aug, 2021

The of() method of java.time.zone.ZoneOffsetTransition class is used to create the object of zone offset transition with the help of local date time, offset before and offset after.

Syntax:

public static ZoneOffsetTransition of(LocalDateTime transition,
                                      ZoneOffset offsetBefore,
                                      ZoneOffset offsetAfter)

Parameter: This method takes the following argument as a parameter.

transition: object of local date time for which transition have to be created.
offsetBefore: object of zone offset for initial transition.
offsetAfter: object of zone offset for final transition.

Return Value: This method returns the object of zone offset transition with the help of local date time, offset before and offset after.
Below are the examples to illustrate the of() method:
Example 1:

Java

// Java program to demonstrate
// of() method

import java.util.*;
import java.io.*;
import java.time.*;
import java.time.chrono.*;
import java.time.zone.*;

public class GFG {
    public static void main(String[] argv)
    {

        // creating and initializing
        // the object of LocalDateTime
        LocalDateTime loc
            = LocalDateTime.of(
                1999, 04, 25,
                03, 24, 45, 0);

        // creating and initializing
        // the object of ZoneOffset
        ZoneOffset off1
            = ZoneOffset.ofTotalSeconds(12);

        // creating and initializing
        // the object of ZoneOffset
        ZoneOffset off2
            = ZoneOffset.ofTotalSeconds(8);

        // creating and initializing
        // ZoneOffsetTransition Object
        // by using of() method
        ZoneOffsetTransition zonetrans1
            = ZoneOffsetTransition.of(
                loc, off1, off2);

        // getting the string representation
        // of this object
        String str
            = zonetrans1.toString();

        // display the result
        System.out.println(
            "zone offset transition : "
            + str);
    }
}

Output:
zone offset transition : Transition[Overlap at 1999-04-25T03:24:45+00:00:12 to +00:00:08]
