IsoChronology prolepticYear() method in Java with Example

The prolepticYear() method of java.time.chrono.JapaneseChronology class is used to retrieve the proleptic year present in the Japanese system of particular Japanese era. 

Syntax:

public int prolepticYear(Era era,
                         int yearOfEra)

Parameter: This method takes the following argument as a parameter.

  • era: which is the object of Japanese Era.
  • yearofEra: which is the year for the particular Japanese era

Return Value: This method returns the proleptic year present in the Japanese system of particular Japanese era. 

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

Example 1: 

Java




// Java program to demonstrate
// prolepticYear() method
 
import java.util.*;

                = JapaneseDate.now();
 
            // getting JapaneseChronology
            // used in JapaneseDate
            JapaneseChronology crono

            // getting prolepticYear for the

                               + proyear);
        }
        catch (DateTimeException e) {
            System.out.println(
                "passed parameter can"
