IsoChronology getId() method in Java with Example

The getId() method of java.time.chrono.IsoChronology class is used to retrieve the identification status for the particular chronology for which getId() method is revoked.

Syntax:

public String getId()

Parameter: This method does not accept any argument as a parameter.

Return Value: This method returns the identification status for the particular chronology for which getId() method is revoked.

Below are the examples to illustrate the getId() method:

Example 1:

// Java program to demonstrate
// getId() method

import java.util.*;
import java.io.*;
import java.time.*;
import java.time.chrono.*;

public class GFG {
    public static void main(String[] argv)
    {
        // creating and initializing
        // LocalDate Object
        LocalDate hidate = LocalDate.now();

        // getting IsoChronology
        // used in LocalDate
        IsoChronology crono
            = hidate.getChronology();

        // getting id of this Chronology
        // by using getId() method
        String id = crono.getId();

        // display the result
        System.out.println("id : " + id);
    }
}

Output:

id : ISO

Example 2:

// Java program to demonstrate
// getId() method

import java.util.*;
import java.io.*;
import java.time.*;
import java.time.chrono.*;

public class GFG {
    public static void main(String[] argv)
    {
        // creating and initializing
        // LocalDate Object
        LocalDate hidate = LocalDate.now(Clock.systemDefaultZone());

        // getting IsoChronology
        // used in LocalDate
        IsoChronology crono
            = hidate.getChronology();

        // getting id of this Chronology
        // by using getId() method
        String id = crono.getId();

        // display the result
        System.out.println("id : " + id);
    }
}

Output:

id : ISO
