Java MinguoDate toEpochDay()用法及代碼示例

java.time.chrono.MinguoDate類的toEpochDay()方法用於獲取當前Minguo日期和0059-01-01之間的紀元天數。

用法:

public long toEpochDay()

參數：此方法不接受任何參數作為參數。

返回值：此方法返回當前Minguo日期和0059-01-01之間的紀元天數

下麵的示例說明了toEpochDay()方法：

範例1：

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 
            // MinguoDate Object 
            MinguoDate hidate = MinguoDate.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:18379

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 
            // MinguoDate Object 
            MinguoDate hidate = MinguoDate.of(59, 01, 01); 
  
            // 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
