Some of the classes that we will need, particularly in libraries, are '''container''' classes, describing data structures made of a number of objects of the same or similar types. Examples of containers include arrays, stacks and lists. The class <code> DEPOSIT_LIST </code> posited in earlier examples describes containers.
It is not hard, with the mechanisms seen so far, to write the class <code> DEPOSIT_LIST </code>, which would include such features as <code> count </code> (query returning the number of deposit objects in the list) and <code> put </code> (command to insert a new deposit object).
