- Type — Cash class implementation of the abstract property defined by the Assets
class. This concrete property must use the same attributes as the abstract version
(that is, SetAccess private).
Methods
The Cash class defines these methods:
- Cash — The constructor assigns property values and supports a default constructor
called with no input arguments. - getCurrentValue — This method is the Cash class implementation of the abstract
method defined by the Assets class. It returns the current value of this asset. - save — This method adds the specified amount of cash to the existing amount and
returns a new Cash object with the current amount. - spend — This method deducts the specified amount from the current amount and
returns a new Cash object with the current amount.
