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); } } } |
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) { 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(- 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); } } } |
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
