public MinguoDate dateYearDay(
  Era era, int yearOfEra, int dayOfYear)

参数：此方法将以下参数作为参数：

• era:这是类型 era 的对象
• 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：此方法根据特定年份和日期的民国日历返回民国日期。

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(
                    MinguoEra.ROC,
                    2018,
                    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 2018-01-24

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(
                    MinguoEra.ROC,
                    1800,
                    -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
