Java.time.chrono.MinguoChronology类的dateYearDay()方法用于根据特定年份和日期的民国日历检索本地日期。
句法：

public MinguoDate dateYearDay(int year,
                              int day)

参数：此方法将以下参数作为参数：

• year：是 MinguoDate 的 year 字段的整数预测年份
• day：是 MinguoDate 的 day 字段的整数天

返回值：此方法根据伊斯兰民国日历返回特定年份和日期的当地日期。
异常：如果给定的日、月和年字段无法形成结构化日期，则此方法抛出DateTimeException 。
以下是说明dateYearDay()方法的示例：
示例 1：

Java

// Java program to demonstrate
// dateYearDay() 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();
 
            // getting MinguoDate for the
            // given date and year field
            // by using dateYearDay() method
            MinguoDate date = crono.dateYearDay(1440, 24);
 
            // display the result
            System.out.println("MinguoDate is: " + date);
        }
        catch (DateTimeException e) {
            System.out.println("passed parameter can "
                               + "not form a date");
            System.out.println("Exception thrown: " + e);
        }
    }
}

输出：

MinguoDate is: Minguo ROC 1440-01-24

示例 2：

Java

// Java program to demonstrate
// dateYearDay() 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();
 
            // getting MinguoDate for the
            // given date and year field
            // by using dateYearDay() method
            MinguoDate date = crono.dateYearDay(2019, -24);
 
            // display the result
            System.out.println("MinguoDate is: " + date);
        }
        catch (DateTimeException e) {
            System.out.println("passed parameter can "
                               + "not form a date");
            System.out.println("Exception thrown: " + e);
        }
    }
}

输出：

passed parameter can not form a date
Exception thrown:
 java.time.DateTimeException:
 Invalid value for DayOfYear
 (valid values 1 - 365/366): -24
