ZoneOffsetTransitionRule getStandardOffset() method in Java with Example

The getStandardOffset() method of java.time.zone.ZoneOffsetTransitionRule class is used to get the object of standard Zone offset with respect to which the transition took place.

Syntax:

public ZoneOffset getStandardOffset()

Parameter: this method does not accept any parameter.

Return Value: This method returns the object of standard Zone offset with respect to which the transition took place.

Below are the examples to illustrate the getStandardOffset() method:

Example 1:

// Java program to demonstrate
// getStandardOffset() 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
        // ZoneOffsetTransitionRule Object
        ZoneOffsetTransitionRule zonetrans1
            = ZoneOffsetTransitionRule
                  .of(
                      Month.JANUARY, 12,
                      DayOfWeek.SUNDAY,
                      LocalTime.of(03, 24, 45),
                      false,
                      ZoneOffsetTransitionRule
                          .TimeDefinition
                          .STANDARD,
                      ZoneOffset.ofTotalSeconds(8),
                      ZoneOffset.ofTotalSeconds(17),
                      ZoneOffset.ofTotalSeconds(12));

        // getting object of Zone offset
        // by using getStandardOffset() method
        ZoneOffset off
            = zonetrans1.getStandardOffset();

        // display the result
        System.out.println(
            "standard Zone Offset : " + off);
    }
}

Output:

standard Zone Offset : +00:00:08

Example 2:

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

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

public class GFG {

        // creating and initializing
        // ZoneOffsetTransitionRule Object
        ZoneOffsetTransitionRule zonetrans1
            = ZoneOffsetTransitionRule
                  .of(
                      Month.JANUARY, 12,
                      DayOfWeek.SUNDAY,
                      LocalTime.of(03, 24, 45),
                      false,
                      ZoneOffsetTransitionRule
                          .TimeDefinition
                          .STANDARD,
                      ZoneOffset.ofTotalSeconds(21),
                      ZoneOffset.ofTotalSeconds(17),
                      ZoneOffset.ofTotalSeconds(12));

        // getting object of Zone offset
        // by using getStandardOffset() method
        ZoneOffset off
            = zonetrans1.getStandardOffset();

        // display the result
        System.out.println(
            "standard Zone Offset : " + off);
    }
}

Output:

standard Zone Offset : +00:00:21
