FACTORY PATTERN - Java EE Design Patterns - page 81

EXERCISES

1. Create a vehicle factory that produces different types of cars and vans by using the abstract
factory pattern.

2. Implement that same vehicle factory as in the previous exercise but use @Produce , qualii ers,
and enum types.

3. By harnessing the power of the CDI container, implement a way to have multiple objects of the
same type and to select the type you require based on type‐safe logic.
