While lists are dynamic objects (i.e. we can add and remove elements from them), arrays are static elements. In other words, if we construct an array with five elements, its size will remain five.
Arrays don't have the general usage that lists do, but they do have their place, so we'll again focus on what's important to know.
Note: Java array indexes are zero-based (i.e., the first element of the array is at index 0, the last element of the array is at index (array.length - 1).
