Working with arrays

In this section we're going to learn about Java arrays. Arrays are Java's most basic and commonly used data structure. Data structures are tools that allow us to store and access sequences of information rather than using individual variables. Variables are great when we have one specific piece of information that we need in our local programming space, but data structures are used when we want to store large or complicated sets or series of information. We're going to start this section with some visual learning modes, and then we'll jump into our NetBeans IDE to write some actual Java code and make use of arrays.
