COP3003 Exam 3 Study Note

Topics covered

Ordered by date introduced 3. chapter 20: Generic Classes and Methods

• There is nothing in the study guide directly on generics
• Likely it will be a part of something else, but not the focus

1. chapter 16: Collections (Interface Collections, Class Collections)

• Lists - Ordered by insertion, duplicates allowed
• Sets - not ordered, only uniques
• Maps - not ordered, key-value association
