Below program illustrates the above method:

Program 1:

// Java code to show the getChronology() function

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

public class ChronoPeriodClass {

    // Function to negate given periods
    static void printChronology(ChronoPeriod p1)
    {

        System.out.println(p1.getChronology());
    }

    // Driver Code
    public static void main(String[] args)
    {
        // Defining period
        int year = 4;
        int months = 11;
        int days = 10;
        ChronoPeriod p1 = Period.of(year, months, days);

        printChronology(p1);
    }
}

Output:

ISO

Program 2:

// Java code to show the getChronology() function

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

public class ChronoPeriodClass {

    // Function to negate given periods
    static void printChronology(ChronoPeriod p1)
    {

        System.out.println(p1.getChronology());
    }

    // Driver Code
    public static void main(String[] args)
    {
        // Defining period
        int year = -4;
        int months = -11;
        int days = -10;
        ChronoPeriod p1 = Period.of(year, months, days);

        printChronology(p1);
    }
}

Output:

ISO
