  • Last Updated : 24 Apr, 2020

The dateYearDay() method of java.time.chrono.MinguoChronology class is used to retrieve the Minguo date according to the Minguo calendar for the particular era.

Syntax:

public MinguoDate 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 propleptic year for the year field of MinguoDate
  • day: which is the integer day for the day field of MinguoDate

Return Value: This method returns the Minguo date according to the Minguo calendar for the particular year and date.

Exception: This method throws DateTimeException – if the given data is unable to form a 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
            // MinguoDate Object
            MinguoDate hidate
                = MinguoDate.now();
  
            // getting MinguoChronology
            // used in MinguoDate
            MinguoChronology crono
                = hidate.getChronology();
  
            // getting MinguoDate for the
            // given date and year field
            // by using dateYearDay() method
            MinguoDate date
                = crono.dateYearDay(
                    MinguoEra.ROC,
                    2018,
                    24);
  
            // display the result
            System.out.println(
                "MinguoDate is: "
                + date);
        }
        catch (DateTimeException e) {
            System.out.println(
                "passed parameter can "
                + "not form a date");
            System.out.println(
                "Exception thrown: " + e);
        }
    }
}
Output:
MinguoDate is: Minguo ROC 2018-01-24

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
            // MinguoDate Object
            MinguoDate hidate
                = MinguoDate.now();
  
            // getting MinguoChronology
            // used in MinguoDate
            MinguoChronology crono
                = hidate.getChronology();
  
            // getting MinguoDate for the
            // given date and year field
            // by using dateYearDay() method
            MinguoDate date
                = crono.dateYearDay(
                    MinguoEra.ROC,
                    1800,
                    -24);
  
            // display the result
            System.out.println(
                "MinguoDate is: "
                + date);
        }
        catch (DateTimeException e) {
            System.out.println(
                "passed parameter can "
                + "not form a date");
            System.out.println(
                "Exception thrown: " + e);
        }
    }
}
Output:
passed parameter can not form a date
Exception thrown:
 java.time.DateTimeException:
 Invalid value for DayOfYear
 (valid values 1 - 365/366): -24
