The Java collections framework is a set of classes and interfaces that implement commonly reusable collection data structures. Though not part of the Java collection framework, arrays allow you to store multiple elements. They are incredibly useful, albeit with significant drawbacks, when used as collection containers. Use this course to practice working with arrays and collections. Start by storing data in an ordered form using arrays. Through this, explore the drawbacks of arrays. Next, examine multi-dimensional arrays and jagged arrays. Finally, create and use the non-parameterized array list to store elements. When you're finished with this course, you'll have a good understanding of how arrays work, their drawbacks, and how the use of collections can overcome many of the limitations of working with arrays.
