In this module, we'll talk about arrays. Arrays are objects in Java that allow us to store a lot of data of the same type. For example, if we had a list of integers, we could put them all in an array to conveniently store them, rather than making hundreds of variables. When coupled with a loop, they can be quite powerful!
Arrays are extremely powerful and are often the first data structure you will learn. They are convenient for storing data, iterating, and manipulating. Their fixed size makes them easy to understand and use. "Data Structures" is a broad term that just means objects in our code that have the ability to store data. There are many other data structures that you may encounter, especially if you decide to take our Data Structures course in the future.
Here are some nice practice problems we've designed:
