Java HijrahDate minus(long, TemporalUnit)用法及代碼示例

java.time.chrono.HijrahDate類的minus()方法用於在從當前hijrah日期中減去一定數量的子句訪問器單元後獲取hijrah日期。

用法:

public HijrahDate minus(long amountToSubtract,
                        TemporalUnit unit)

參數：此方法將以下參數作為參數：

amountToSubstract:這是將從當前hijrah日期減去的時間單位的值。
unit:這是時間單位或計時單位的對象。

返回值：此方法從當前的Hijrah日期中減去一定數量的臨時訪問器單元後，返回Hijrah日期。

下麵是說明minus()方法的示例：

範例1：

Java

// Java program to demonstrate minus() 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.now(); 
  
            // Display the result 
            System.out.println("old hijrah date:"
                               + hidate); 
  
            // Substracting hijrah date 
            // by using minus() method 
            HijrahDate newdate 
                = hidate.minus( 
                    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); 
        } 
    } 
}

輸出：

old hijrah date:Hijrah-umalqura AH 1441-06-25
new hijrah date:Hijrah-umalqura AH 1441-06-03

範例2：

Java

// Java program to demonstrate minus() 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 { 
            // Dreating and initializing 
            // HijrahDate Object 
            HijrahDate hidate 
                = HijrahDate.now(); 
  
            // Display the result 
            System.out.println("old hijrah date:"
                               + hidate); 
  
            // Substracting hijrah date 
            // by using minus() method 
            HijrahDate newdate 
                = hidate.minus( 
                    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); 
        } 
    } 
}

輸出：

old hijrah date:Hijrah-umalqura AH 1441-06-25
new hijrah date:Hijrah-umalqura AH 1401-06-25
