The normalized() method of the ZoneId class in Java is used to normalize the time-zone ID and returns a ZoneOffset where possible.
The method returns a normalized ZoneId that can be used in place of this ID. The normalization process checks if the rules of this ZoneId have a fixed offset. If ZoneId has fixed offset then the ZoneOffset equal to that offset is returned. Otherwise, this is returned.
Syntax:
public ZoneId normalized()
Parameters: This method accepts nothing.
Return value: This method returns the time-zone unique ID.
Below programs illustrate the normalized() method:
Program 1:
// Java program to demonstrate// ZoneId.normalized() method  import java.time.*;  public class GFG {    public static void main(String[] args)    {          // create ZoneId object        ZoneId zoneId            = ZoneId.of("Europe/Paris");          // get and print normalised zoneId        System.out.println("Normalised zoneId: "                           + zoneId.normalized());    }} | 
Normalised zoneId: Europe/Paris
Program 2:
// Java program to demonstrate// ZoneId.normalized() method  import java.time.*;  public class GFG {    public static void main(String[] args)    {          // create ZoneId object        ZoneId zoneId            = ZoneId.of("Asia/Calcutta");          // get and print Id        System.out.println("Normalised zoneId: "                           + zoneId.normalized());    }} | 
Normalised zoneId: Asia/Calcutta
