Java HijrahChronology dateYearDay()函数用法及代码示例

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

用法:

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

参数：此方法采用以下参数作为参数。

era:这是Era类型的对象
year:这是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日历返回本地日期。

异常：如果日，月和年的给定字段无法形成结构化日期，则此方法将引发DateTimeException。

下面是说明dateYearDay()方法的示例：

范例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

范例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
