The getId() method of the ZoneId class in Java is used to get the unique time-zone ID which uniquely defines this object.

Parameters: This method accepts nothing.

Return value: This method returns the time-zone unique ID.

Below programs illustrate the getId() method:
Program 1:

// Java program to demonstrate
// ZoneId.getId() 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 Id
        System.out.println("Id: "
                           + zoneId.getId());
    }
}

Output:

Id: Europe/Paris

Program 2:

// Java program to demonstrate
// ZoneId.getId() 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("Id: "
                           + zoneId.getId());
    }
}
