Milliseid Java sisseehitatud kogumissideseid olete oma praktikas kasutanud?

In Java, the following built-in interfaces are often used for working with collections:

• List — an ordered list of elements that allows duplicates. Examples: ArrayList, LinkedList.
• Set — a collection of unique elements without a defined order. Examples: HashSet, TreeSet.
• Map — a key-value mapping, where keys are unique. Examples: HashMap, TreeMap.
• Queue — a queue that maintains the order of element processing. Examples: LinkedList, PriorityQueue.

In practice, List is often used for storing ordered data, Set for unique elements (e.g., for filtering duplicates), and Map for fast key-based lookups (e.g., caching data).
