The dateYearDay() method of java.time.chrono.JapaneseChronology class is used to retrieve the Japanese date according to the japanese calendar for the particular era. Syntax:
public JapaneseDate 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 proleptic year for the year field of JapaneseDate
- day: which is the integer day for the day field of JapaneseDate
Return Value: This method returns the Japanese date according to the Japanese 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
// JapaneseDate Object
JapaneseDate hidate
= JapaneseDate.now();
// getting JapaneseChronology
// used in JapaneseDate
JapaneseChronology crono
= hidate.getChronology();
// getting JapaneseDate for the
// given date and year field
// by using dateYearDay() method
JapaneseDate date
= crono.dateYearDay(
JapaneseEra.HEISEI,
2018 ,
24 );
// display the result
System.out.println(
"JapaneseDate is: "
+ date);
}
catch (DateTimeException e) {
System.out.println(
"passed parameter can "
+ "not form a date" );
System.out.println(
"Exception thrown: " + e);
}
}
} |
Output:
JapaneseDate is: Japanese Heisei 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)
{

JapaneseDate hidate
= JapaneseDate.now();
// getting JapaneseChronology
// used in JapaneseDate
JapaneseChronology crono
= hidate.getChronology();
// getting JapaneseDate for the
// given date and year field
// by using dateYearDay() method
JapaneseDate date
= crono.dateYearDay(
JapaneseEra.MEIJI,
2018 ,
24 );
// display the result
System.out.println(
"JapaneseDate 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 parameters
