Overview. These slides are teachable, include a short data-processing activity at the end and are completely editable to your liking. Complete with animations explaining all the various ArrayList function sets required by the AP extremely useful for visualizing how collections are affected depending on the methods used.

Objective: Define and effectively use arrays and arrayLists in Java

Guiding Questions

• Differentiate the characteristics between an array and an arrayList: understand when to use one over the other
• Initialize, Add, Edit, Remove and Access elements of an array
• Effectively use the arrayList function set
• Efficient traversal of arrays and correctly remove elements from an arrayList
• Use for, while and the enhanced for-loop to traverse arrays

Vocabulary and functions

These slides closely follow the content set by College Boards AP CS A Unit 6 and Unit 7, with an emphasis on Unit 7 (ArrayLists)

• 7.1 - Introduction to ArrayLists
• 7.1 - ArrayList Methods
