Java中的 MinguoChronology dateEpochDay() 方法示例

Java.time.chrono.MinguoChronology类的dateEpochDay()方法用于根据民国日历系统从大纪元获取当地日期。
句法：

public MinguoDate dateEpochDay(long epochDay)

参数：该方法以long类型的epochDay作为参数。
返回值：该方法从大纪元开始根据民国历系统返回本地日期。
异常：如果给定的纪元日无法形成结构化日期，则此方法抛出DateTimeException 。
以下是说明dateEpochDay()方法的示例：
示例 1：

Java

// Java program to demonstrate
// Minguo() 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 MinguoDate Object
            MinguoDate hidate = MinguoDate.now();
 
            // getting MinguoChronology used in MinguoDate
            MinguoChronology crono = hidate.getChronology();
 
            // display the result
            System.out.println("current MinguoDate is: "
                               + hidate);
 
            // getting MinguoDate for the
            // given TemporalAccessor object
            // by using date() method
            hidate = crono.dateEpochDay(23456);
 
            // display the result
            System.out.println("\nMinguoDate(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 MinguoDate is: Minguo ROC 110-06-22

MinguoDate(according to ephochday) is: Minguo ROC 123-03-22

                               + " not form a date");
            System.out.println("Exception thrown: " + e);
        }
    }
}

输出

current MinguoDate is: Minguo ROC 110-06-22

MinguoDate(according to ephochday) is: Minguo ROC 701-03-24
