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
