IsoChronology dateYearDay(int, int) method in Java with Example
The dateYearDay() method of java.time.chrono.IsoChronology class is used to retrieve the local date according to the Iso calendar for the particular year and date.
Syntax:
public LocalDate dateYearDay(int prolepticYear, int dayOfYear)
Parameter: This method takes the following arguments as parameter:
- year: which is the integer proleptic year for the year field of LocalDate
- day: which is the integer day for the day field of LocalDate
Return Value: This method returns the local date according to the Iso calendar for the particular year and date.
Below are the examples to illustrate the dateYearDay() method:
Example 1:
Java
// Java program to demonstrate // dateYearDay() 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 LocalDate for the // given date and year field // by using dateYearDay() method LocalDate date = crono.dateYearDay( 1440 , 24 ); // display the result System.out.println( "LocalDate is: " + date); } catch (DateTimeException e) { System.out.println( "passed parameter can " + "not form a date" ); System.out.println( "Exception thrown: " + e); } } } |
Output:
LocalDate is: 1440-01-24
Example 2:
Java
// Java program to demonstrate // dateYearDay() 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 LocalDate for the // given date and year field // by using dateYearDay() method LocalDate date = crono.dateYearDay( 999999999 , 32 ); // display the result System.out.println( "LocalDate is: " + date); } catch (DateTimeException e) { System.out.println( "passed parameter can " + "not form a date" ); System.out.println( "Exception thrown: " + e); } } } |
Output:
LocalDate is: +999999999-02-01
