Figure 10.29b Class that implements a toy-bear store—part B Embedded Driver
At the bottom of the BearStore class, we’ve embedded the program’s driver, main. It instantiates a BearStore object, adds three standard bears to the bear store, adds two user-specified bears to the bear store, and then displays the store’s inventory of bears by calling displayInventory. In displaying the store’s inventory, the displayInventory method accesses each bear in the bears ArrayList with the help of a for-each loop. In the next subsection, you’ll learn about for-each loop details.
