Unit 7 refers to a specific section or module of study in the AP Computer Science A curriculum that focuses on topics such as arrays, ArrayLists, and searching algorithms.
congrats on reading the definition of Unit 7. now let's actually learn it.
Arrays: Arrays are data structures that store multiple values of the same type. They allow for efficient storage and retrieval of elements.
ArrayLists: ArrayLists are similar to arrays but have dynamic size, meaning they can grow or shrink as needed. They provide additional flexibility compared to regular arrays.
Searching Algorithms: Searching algorithms are methods used to find a specific element within a collection of data. Examples include linear search and binary search.
