ChronoZonedDateTime getChronology() method in Java with Examples

The getChronology() method of ChronoZonedDateTime interface in Java gets the chronology of this date, which is the ISO calendar system.

Syntax:

default IsoChronology getChronology()

Parameter: This method does not accept any parameter.

Return Value: It returns the ISO chronology and not null.

Below programs illustrate the get() method:

Program 1:

// Java program to demonstrate
// ChronoZonedDateTime.get() method

import java.time.*;
import java.time.chrono.*;
import java.time.temporal.ChronoField;

public class GFG {
    public static void main(String[] args)
    {

        // create a ChronoZonedDateTime object
        ChronoZonedDateTime zonedDT
            = ZonedDateTime.parse(
                "2018-12-06T19:21:12.123+05:30[Asia/Calcutta]");

        // print result
        System.out.println("Chronology: "
                           + zonedDT.getChronology());
    }
}

Output:

Chronology: ISO

Program 2:

// Java program to demonstrate
// ChronoZonedDateTime.get() method

import java.time.*;
import java.time.chrono.*;
import java.time.temporal.ChronoField;

public class GFG {
    public static void main(String[] args)
    {

        // create a ChronoZonedDateTime object
        ChronoZonedDateTime zonedDT
            = ZonedDateTime.parse(
                "2018-10-25T23:12:31.123+02:00[Europe/Paris]");

        System.out.println("Chronology: "
                           + zonedDT.getChronology());
    }
}

Output:

Chronology: ISO
