HijrahDate minus(long, TemporalUnit) method in Java with Example

The minus() method of java.time.chrono.HijrahDate class is used to get the hijrah date after subtracting an amount of temporal accessor unit from the current hijrah date.

Syntax:

public HijrahDate minus(long amountToSubtract,
                        TemporalUnit unit)

Parameter: This method takes the following argument as a parameter:  

• amountToSubtract: which is the value of temporal unit which is going to subtract from the current hijrah date.
• unit: which is the object of temporal unit or chrono unit.

Return Value: This method returns the Hijrah date after subtracting an amount of temporal accessor unit from current Hijrah date.

Below are the examples to illustrate the minus() method:

Example 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);

            // Subtracting 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);
        }
    }
}

Output:

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

Example 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);

            // Subtracting 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);
        }
    }
}

Output:

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