ZoneOffset of(String) method in Java with Examples

Last Updated : 11 Dec, 2018

The

method of

in

is used to obtain an instance of ZoneOffset using the offsetId passed as the parameter. This method takes the offsetId as parameter in the form of String and converts it into the ZoneOffset. The ID of the returned offset will be normalized to one of the formats described by getId(). The list of String offsetId accepted by this method are as follows:

• Z - for UTC
• +h
• +hh
• +hh:mm
• -hh:mm
• +hhmm
• -hhmm
• +hh:mm:ss
• -hh:mm:ss
• +hhmmss
• -hhmmss
Note: ± means either the plus or minus symbol. And the maximum supported range is from +18:00 to -18:00 inclusive. Syntax:

public static ZoneOffset of(String offsetId)

Parameters: This method accepts a parameter offsetId which is String to be parsed into an ZoneOffset instance. Return Value: This method returns a ZoneOffset instance parsed from the specified offsetId. Exception: This method throws DateTimeException if the offset ID is invalid. Below examples illustrate the ZoneOffset.of() method: Example 1: Java

// Java code to illustrate of() method

import java.time.*;

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

        // Get the offset ID
        String offsetId = "Z";

        // ZoneOffset using of() method
        ZoneOffset zoneOffset
            = ZoneOffset.of(offsetId);

        System.out.println(zoneOffset);
    }
}

Example 2: To demonstrate DateTimeException Java

// Java code to illustrate of() method

import java.time.*;

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

        // Get the invalid offset ID
        String offsetId = "10:10";

        try {
            // ZoneOffset using of() method
            ZoneOffset zoneOffset
                = ZoneOffset.of(offsetId);
        }

        catch (Exception e) {
            System.out.println(e);
        }
    }
}

Output:

java.time.DateTimeException: Invalid ID for ZoneOffset, non numeric characters found: 10:10
