The dateYearDay() method of java.time.chrono.IsoChronology class is used to retrieve the local date according to the Iso calendar for the particular era.
Syntax:
public LocalDate dateYearDay(Era era,
int yearOfEra,
int dayOfYear)
Parameter: This method takes the following arguments as parameter.
- era: which is the object of type Era
- year: which is the integer 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 era.
Below are the examples to illustrate the dateYearDay() method:
Example 1:
// 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(                    IsoEra.BCE, 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: -1439-01-24
Example 2:
// 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(                    IsoEra.BCE, 0000, 30);              // 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: 0001-01-30
