What are the main differences between List, Set, and Map in Java Collections?
In Java Collections, List allows duplicates and maintains order, Set does not allow duplicates and is unordered, while Map stores key-value pairs.
Can you give examples of when to use each type?
Use List when you need ordered elements, Set for unique elements, and Map for associating keys with values.
What are the performance implications of using these collections?
Lists have O(1) access time, Sets have O(1) for add/remove, and Maps have O(1) for key lookups, but performance can vary based on implementation.
Are there any specific implementations of these collections I should know about?
Yes, for List, you can use ArrayList or LinkedList; for Set, HashSet or TreeSet; and for Map, HashMap or TreeMap.
