Parameter

A method may require one or more parameters. For example a print method for a cheque document may require 3 parameters such as ‘Payee’, ‘Cheque Number’ and ‘Amount’. The same method may be overridden more than once with each override having a different number of parameters. These are then different overrides and can use totally different code. Multiple overrides should be used with care and with common sense, beware of trying to be too clever.
