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)
    {
        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);
        }
    }
}


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
