带有示例的Java中的 HijrahDate plus(long, TemporalUnit) 方法

Java.time.chrono.HijrahDate类的plus()方法用于在将一定数量的时间存取单元与当前回历日期相加后获取回历日期。

句法：

public HijrahDate plus(long amount,
                       TemporalUnit unit)

参数：此方法将以下参数作为参数：

• 数量：这是要与当前回历日期相加的时间单位数量。
• 单位：这是时间单位或计时单位的对象。

返回值：该方法在将一定数量的时间存取单元与当前的回历日期相加后返回回历日期。

以下是说明plus()方法的示例：

示例 1：

Java

// Java program to demonstrate
// plus() method
  
import java.util.*;
import java.io.*;
import java.time.*;
import java.time.chrono.*;
import java.time.temporal.*;
  
public class GFG {
    public static void main(String[] argv)
    {
        try {
            // creating and initializing
            // HijrahDate Object
            HijrahDate hidate
                = HijrahDate.of(1345, 06, 23);
  
            // display the result
            System.out.println("old hijrah date : "
                               + hidate);
  
            // adding some amount in hijrah date
            // by using minus() method
            HijrahDate newdate
                = hidate.plus(
                    22,
                    ChronoUnit.DAYS);
  
            // display the result
            System.out.println("new hijrah date : "
                               + newdate);
        }
        catch (DateTimeException e) {
            System.out.println("passed parameter can"
                               + " not form a date");
            System.out.println("Exception thrown: "
                               + e);
        }
    }
}

输出：

old hijrah date : Hijrah-umalqura AH 1345-06-23
new hijrah date : Hijrah-umalqura AH 1345-07-16

            System.out.println("old hijrah date : "
                               + hidate);
  
            // adding some amount in hijrah date
            // by using minus() method
            HijrahDate newdate
                = hidate.plus(
                    4,
                    ChronoUnit.DECADES);
  
            // display the result
            System.out.println("new hijrah date : "
                               + newdate);
        }
        catch (DateTimeException e) {
            System.out.println("passed parameter can"
                               + " not form a date");
            System.out.println("Exception thrown: "
                               + e);
        }
    }
}

输出：

old hijrah date : Hijrah-umalqura AH 1345-06-23
new hijrah date : Hijrah-umalqura AH 1385-06-23
