Java HijrahDate plus(long, TemporalUnit)用法及代码示例

java.time.chrono.HijrahDate类的plus()方法用于在将一定数量的临时访问器单元与当前hijrah日期相加后，获取hijrah日期。

用法:

public HijrahDate plus(long amount,
                       TemporalUnit unit)

参数：此方法将以下参数作为参数：

amount:这是将要与当前希拉日日期相加的时间单位的数量。
unit:这是时间单位或计时单位的对象。

返回值：在将一定数量的临时访问器单元与当前Hijrah日期相加后，此方法将返回Hijrah日期。

下面是说明plus()方法的示例：

范例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

范例2：

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( 
                    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
