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

Example 1:

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

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

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

            // getting ThaiBuddhistChronology
            // used in ThaiBuddhistDate
            ThaiBuddhistChronology crono
                = hidate.getChronology();

            // getting prolepticYear for the
            // given year of Era
            // by using prolepticYear() method
            int proyear
                = crono.prolepticYear(
                    ThaiBuddhistEra.BE,
                    1444);

            // display the result
            System.out.println("proleptic Year is: "
                               + proyear);
        }
        catch (DateTimeException e) {
            System.out.println(
                "passed parameter can"
                + " not form a date");
            System.out.println(
                "Exception thrown: " + e);
        }
    }
}

Output:

proleptic Year is: 1444

Example 2:

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

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

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

            // ThaiBuddhistDate Object
            ThaiBuddhistDate hidate
                = ThaiBuddhistDate.now();

            // getting ThaiBuddhistChronology
            // used in ThaiBuddhistDate
            ThaiBuddhistChronology crono
                = hidate.getChronology();

            // getting prolepticYear for the
            // given year of Era
            // by using prolepticYear() method
            int proyear
                = crono.prolepticYear(
                    ThaiBuddhistEra.BEFORE_BE,
                    1444);

            // display the result
            System.out.println("proleptic Year is: "
                               + proyear);
        }
        catch (DateTimeException e) {
            System.out.println(
                "passed parameter can"
                + " not form a date");
            System.out.println(
                "Exception thrown: " + e);
        }
    }
}

Output:

proleptic Year is: -1443
