Main Idea

** ArrayLists are used to store data and algorithms and can be used to access, traverse, and sort through this data.**

Why ArrayLists?

ArrayLists don’t have a fixed size like Arrays and we can add and remove items from them, making them more verstaile and having more functions

Key Topics:

Topic 7.1 - Intro to Arraylists (Sri) Topic 7.2 - Methods with Arraylists (Sri & Saathvik) Topic 7.3 - Traversing ArrayLists (Tanav) Topic 7.4 - Developing Algorithms Using ArrayLists (Tanav) Topic 7.5 - Searching (Aidan) Topic 7.6 - Sorting (Aidan) Topic 7.7 - Ethical Issues Around Data Collection (Saathvik)
