ZoneId normalized() method in Java with Examples

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());
    }
}

Output:

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());
    }
}

Output:

Normalised zoneId: Asia/Calcutta
