MinguoChronology prolepticYear() method in Java with Example

  • Last Updated : 24 Apr, 2020

The prolepticYear() method of java.time.chrono.MinguoChronology class is used to retrieve the proleptic year present in the Minguo system of particular Minguo 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 Minguo Era.
  • yearofEra: which is the year for the particular Minguo era

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

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
            // MinguoDate Object
            MinguoDate hidate
                = MinguoDate.now();
  
            // getting MinguoChronology
            // used in MinguoDate
            MinguoChronology crono
                = hidate.getChronology();
  
            // getting prolepticYear for the
            // given year of Era
            // by using prolepticYear() method
            int proyear
                = crono.prolepticYear(
                    MinguoEra.ROC,
                    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)
    {
        try {
            // creating and initializing
            // MinguoDate Object
            MinguoDate hidate
                = MinguoDate.now();
  
            // getting MinguoChronology
            // used in MinguoDate
            MinguoChronology crono
                = hidate.getChronology();
  
            // getting prolepticYear for the
            // given year of Era
            // by using prolepticYear() method
            int proyear
                = crono.prolepticYear(
                    MinguoEra.BEFORE_ROC,
                    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
