The prolepticYear() method of java.time.chrono.IsoChronology class is used to retrieve the proleptic year present in the Iso system of particular hijrah 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 iso Era.
- yearofEra: which is the year for the particular iso era.
Return Value: This method returns the proleptic year present in the iso system of particular iso 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 // LocalDate Object LocalDate hidate = LocalDate.now(); // getting IsoChronology used in LocalDate IsoChronology crono = hidate.getChronology(); // getting prolepticYear for the // given year of Era // by using prolepticYear() method int proyear = crono.prolepticYear(IsoEra.CE, 2020); // 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: 2020
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 // LocalDate Object LocalDate hidate = LocalDate.now(); // getting IsoChronology used in LocalDate IsoChronology crono = hidate.getChronology(); // getting prolepticYear for the // given year of Era // by using prolepticYear() method int proyear = crono.prolepticYear(IsoEra.BCE, 1980); // 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: -1979
