import java.time.*;
import java.time.chrono.*;
public class GFG {
public static void main(String[] argv)
{
try {
// creating and initializing
// JapaneseDate Object
JapaneseDate hidate
= JapaneseDate.now();
// getting JapaneseChronology
// used in JapaneseDate
JapaneseChronology crono
= hidate.getChronology();
// getting prolepticYear for the
// given year of Era
// by using prolepticYear() method
int proyear
= crono.prolepticYear(
JapaneseEra.HEISEI,
1444);
// display the result
System.out.println("proleptic Year is: "
+ proyear);
}
catch (DateTimeException e) {
System.out.println(
