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 teporal 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:

  • amountToSubstract: which is the value of temporal unit which is going to substracted 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:

                               + newdate);
        }
        catch (DateTimeException e) {
            System.out.println("passed parameter can"
                               + " not form a date");
            System.out.println("Exception thrown: "
                               + e);
        }
    }
}
