ZoneId ofOffset() method in Java with Examples

The ofOffset() method of the ZoneId class used to obtain an instance of ZoneId wrapping an offset.If the prefix passed in this method is “GMT”, “UTC”, or “UT” a ZoneId with the prefix then the non-zero offset is returned and If the prefix is empty “” then the ZoneOffset is returned.
Syntax:

public static ZoneId ofOffset(String prefix,
                              ZoneOffset offset)

Parameters: This method accepts two parameters prefix and offset where prefix represents the time-zone ID and offset represents the offset.
Return value: This method returns the zoneId.
Exception: This method throws an IllegalArgumentException if the prefix is not one of “GMT”, “UTC”, or “UT”, or “”.
Below programs illustrate the ofOffset() method:
Program 1:

Java

// Java program to demonstrate
// ZoneId.ofOffset() method
 
import java.time.*;
 
public class GFG {

    public static void main(String[] args)

    {
 
        // create ZoneId object

        ZoneId zoneId

            = ZoneId.ofOffset("UTC",

                              ZoneOffset.UTC);
 
        // print result

        System.out.println("ZoneId:"

                           + zoneId);

    }
}

Output:

ZoneId:UTC

Program 2:

Java

// Java program to demonstrate
// ZoneId.ofOffset() method
 
import java.time.*;

public class GFG {

    public static void main(String[] args)

    {
 
        // create ZoneId object

        ZoneId zoneId

            = ZoneId.ofOffset("GMT",

                              ZoneOffset.MAX);
 
        // print result

        System.out.println("ZoneId:"

                           + zoneId);

    }
}
