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

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

Syntax: 

public MinguoDate minus(long amountToAdd,
                        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 Minguo date.
  • unit: which is the object of temporal unit or chrono unit.

Return Value: This method returns the Minguo date after subtracting an amount of temporal accessor unit from current Minguo 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);
        }
    }
}
