带有示例的Java中的 HijrahChronology dateYearDay() 方法：设置 2

Java.time.chrono.HijrahChronology类的dateYearDay()方法用于根据特定时代的伊斯兰回历检索本地日期。

句法：

public HijrahDate dateYearDay(Era era,
                              int year,
                              int day)

参数：此方法将以下参数作为参数。

• era:这是 Era 类型的对象
• year： HijrahDate 的 year 字段的整数年
• day：这是 HijrahDate 的 day 字段的整数天

返回值：此方法根据特定时代的伊斯兰回历返回当地日期。

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 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
            // HijrahDate Object
            HijrahDate hidate = HijrahDate.now();
  
            // getting HijrahChronology
            // used in HijrahDate
            HijrahChronology crono
                = hidate.getChronology();
  
            // getting HijrahDate for the
            // given date and year field
            // by using dateYearDay() method
            HijrahDate date
                = crono.dateYearDay(
                    HijrahEra.AH, 1440, 24);
  
            // display the result
            System.out.println("HijrahDate is: "
                               + date);
        }
        catch (DateTimeException e) {
            System.out.println("passed parameter can "
                               + "not form a date");
            System.out.println("Exception thrown: " + e);
        }
    }
}

输出：

HijrahDate is: Hijrah-umalqura AH 1440-01-24

示例 2：

// 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
            // HijrahDate Object
            HijrahDate hidate
                = HijrahDate.now();
  
            // getting HijrahChronology
            // used in HijrahDate
            HijrahChronology crono
                = hidate.getChronology();
  
            // getting HijrahDate for the
            // given date and year field
            // by using dateYearDay() method
            HijrahDate date
                = crono.dateYearDay(
                    HijrahEra.AH, 2019, 24);
  
            // display the result
            System.out.println("HijrahDate 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 Hijrah date, year: 2019, month: 1
