Understanding Eclipse Collections: An Analogy
Let’s simplify Eclipse Collections by comparing it to a toolbox. Imagine you have various tools such as hammers, screwdrivers, and pliers — each designed for specific tasks. Similarly, Eclipse Collections provides several specialized collection types (like List, Set, Map, etc.) each tailored for different data management requirements.
Just as a carpenter might reach for a hammer to drive a nail but use a screwdriver for a screw, you can choose the right collection type based on whether you need duplicates (like in a Bag), or unique items (like in a Set).
