Java 中的 minuo 年表 dateEpochDay()方法，示例

原文:https://www . geeksforgeeks . org/minguoberythro-datepochday-method-in-Java-with-example/

Java . time . chrono . Minguo 年表类的 dateEpochDay() 方法用于从大纪元日开始，根据 Minguo 日历系统获取当地日期。 语法:

public MinguoDate dateEpochDay(long epochDay)

参数:该方法以 long 类型的 epochDay 为参数。 返回值:此方法从大纪元日开始根据民国历法系统返回当地日期。 异常:如果给定的纪元日无法形成结构化日期，则该方法抛出日期时间异常。 以下是举例说明datepochday()方法: 例 1:

Java 语言(一种计算机语言，尤用于创建网站)

// 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);
        }
    }
}

Output

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);
        }
    }
}

Output

current MinguoDate is: Minguo ROC 110-06-22

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