Java

// Java program to demonstrate 
// toEpochDay() method 
  
import java.util.*; 
import java.io.*; 
import java.time.*; 
import java.time.chrono.*; 
import java.time.temporal.*; 
  
public class GFG { 
    public static void main(String[] argv) 
    { 
        try { 
            // Creating and initializing 
            // HijrahDate Object 
            HijrahDate hidate = HijrahDate.now(); 
  
            // Getting no of ephoch days present 
            // by using toEpochDay() method 
            long length = hidate.toEpochDay(); 
  
            // Display the result 
            System.out.println("EpochDay:"
                               + length); 
        } 
        catch (DateTimeException e) { 
            System.out.println("passed parameter can"
                               + " not form a date"); 
            System.out.println("Exception thrown:"
                               + e); 
        } 
    } 
}

輸出：

EpochDay:18311

範例2：

Java

// Java program to demonstrate 
// toEpochDay() method 
  
import java.util.*; 
import java.io.*; 
import java.time.*; 
import java.time.chrono.*; 
import java.time.temporal.*; 
  
public class GFG { 
    public static void main(String[] argv) 
    { 
        try { 
            // Creating and initializing 
            // HijrahDate Object 
            HijrahDate hidate 
                = HijrahDate.of(1389, 10, 22); 
  
            // Getting no of ephoch days present 
            // by using toEpochDay() method 
            long length = hidate.toEpochDay(); 
  
            // Display the result 
            System.out.println("EpochDay:"
                               + length); 
        } 
        catch (DateTimeException e) { 
            System.out.println("passed parameter can"
                               + " not form a date"); 
            System.out.println("Exception thrown:"
                               + e); 
        } 
    } 
}

輸出：

EpochDay:0
