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
