Problems

1. Create a series of CRC cards for World’s Trend Catalog Division. Once an order is placed, the order
fulfillment crew takes over and checks for availability, fills the order, and calculates the total amount
of the order. Use five CRC cards, one for each of the following classes: order, order fulfillment,
inventory, product, and customer. Complete the section on classes, responsibilities, and collaborators.
2. Finish the CRC cards in Problem 1 by creating Object Think statements and property names for each
of the five classes.
