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() methodimport 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() methodimport 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); }} |
Output:
ZoneId:GMT+18:00
