What are some examples of modern collections in Java?
Java offers several modern collection types, such as List, Set, and Map. For instance, ArrayList and HashSet are widely used.
Can you explain the differences between ArrayList and LinkedList?
Sure! ArrayList is backed by a dynamic array, making it faster for random access, while LinkedList uses a doubly linked list, which is better for insertions and deletions.
What about the differences between HashSet and TreeSet?
HashSet is unordered and allows null elements, while TreeSet is ordered and does not allow nulls. TreeSet also provides a sorted view of the elements.
Are there any new features in Java collections since Java 8?
Yes! Java 8 introduced streams, which allow for functional-style operations on collections, making it easier to process data.
