The dateEpochDay() method of java.time.chrono.JapaneseChronology class is used get the Japanese date according to Japanese calendar system from the Epoch Day.
Syntax:
public JapaneseDate dateEpochDay(long epochDay)
Parameter: This method takes the epochDay of type long as a parameter.
Return Value: This method returns the local date according to Japanese calendar system from another TemporalAccessor object.
Exception: This method throws DateTimeException if this epoch day is unable to create the Japanese date.
Below are the examples to illustrate the dateEpochDay() method:
Example 1:
Java
// Java program to demonstrate // dateEpochDay() 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();
// display the result
System.out.println( "current JapaneseDate is: "
+ hidate);
// getting JapaneseDate for the
// given TemporalAccessor object
// by using dateEpochDay() method
hidate = crono.dateEpochDay( 23456 );
// display the result
System.out.println( "\nJapaneseDate(according "
+ "to epochday) is: "
+ hidate);
}
catch (DateTimeException e) {
System.out.println( "passed parameter can"
+ " not form a date" );
System.out.println( "Exception thrown: " + e);
}
}
} |
Output
current JapaneseDate is: Japanese Reiwa 5-02-03 JapaneseDate(according to epochday) is: Japanese Reiwa 16-03-22
Example 2:
Java
// Java program to demonstrate // dateEpochDay() method import java.util.*;
import java.io.*;
import java.time.*;
import java.time.chrono.*;
public class GFG {
public static void main(String[] argv)

= hidate.getChronology();
// display the result
System.out.println( "current JapaneseDate is: "
+ hidate);
// getting JapaneseDate for the
// given TemporalAccessor object
// by using dateEpochDay() method
hidate = crono.dateEpochDay(- 999999999 );
// display the result
System.out.println( "\nJapaneseDate(according "
+ "to epochday) is: "
+ hidate);
}
catch (DateTimeException e) {
System.out.println( "passed parameter can"
+ " not form a date" );
System.out.println( "Exception thrown: " + e);
}
}

Output
current JapaneseDate is: Japanese Reiwa 5-02-03 passed parameter can not form a date Exception thrown: java.time.DateTimeException: JapaneseDate before Meiji 6 is not supported
