Other Asset Methods The asset class provides inherited data storage for its child classes, but is not instanced directly. The set, get, and display methods provide access to the stored data. It is not necessary to implement the full complement of methods for asset objects (such as converters, end, and subsindex) since only the child classes access the data. The Asset Constructor Method The asset class is based on a structure array with four fields: • descriptor – Identifier of the particular asset (e.g., stock name, savings account number, etc.) - • date – The date the object was created (calculated by the date command) • type – The type of asset (e.g., savings, bond, stock) • currentValue - The current value of the asset (calculated from subclass data) - - This information is common to asset child objects (stock, bond, and savings), so it is handled from the parent object to avoid having to define the same fields in each child class. This is particularly helpful as the number of child classes increases.

The asset class provides inherited data storage for its child classes, but is not
instanced directly. The set, get, and display methods provide access to the
stored data. It is not necessary to implement the full complement of methods
for asset objects (such as converters, end, and subsindex) since only the child
classes access the data.
The Asset Constructor Method
The asset class is based on a structure array with four fields:
Identifier of the particular asset (e.g., stock name, savings
• descriptor –
account number, etc.)
• date -The date the object was created (calculated by the date command)
• type - The type of asset (e.g., savings, bond, stock)
• currentValue
The current value of the asset (calculated from subclass
data)
This information is common to asset child objects (stock, bond, and savings), so
it is handled from the parent object to avoid having to define the same fields in
each child class. This is particularly helpful as the number of child classes
increases.
