以下是说明dateEpochDay()方法的示例：
示例 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
            // ThaiBuddhistDate Object
            ThaiBuddhistDate hidate
                = ThaiBuddhistDate.now();
 
            // getting ThaiBuddhistChronology
            // used in ThaiBuddhistDate
            ThaiBuddhistChronology crono
                = hidate.getChronology();
 
            // display the result
            System.out.println("current ThaiBuddhistDate is: "
                               + hidate);
 
            // getting ThaiBuddhistDate for the
            // given TemporalAccessor object
            // by using date() method
            hidate = crono.dateEpochDay(23456);
 
            // display the result
            System.out.println("\nThaiBuddhistDate(according "
                               + "to ephochday) is: "
                               + hidate);
        }
        catch (DateTimeException e) {
            System.out.println("passed parameter can"
                               + " not form a date");
            System.out.println("Exception thrown: " + e);
        }
    }
}

输出

current ThaiBuddhistDate is: ThaiBuddhist BE 2564-06-25

ThaiBuddhistDate(according to ephochday) is: ThaiBuddhist BE 2577-03-22

        }
        catch (DateTimeException e) {
            System.out.println("passed parameter can"
                               + " not form a date");
            System.out.println("Exception thrown: " + e);
        }
    }
}

输出

current ThaiBuddhistDate is: ThaiBuddhist BE 2564-06-25

ThaiBuddhistDate(according to ephochday) is: ThaiBuddhist BEFORE_BE 271279-04-21
