What are Java Collections and how do they work?
Java Collections are frameworks that provide data structures and algorithms to store and manipulate groups of objects.
Can you explain the different types of collections in Java?
Sure! The main types are List, Set, and Map. Each serves different purposes and has unique characteristics.
What is the difference between a List and a Set?
A List allows duplicate elements and maintains order, while a Set does not allow duplicates and does not guarantee order.
How do I choose the right collection for my needs?
It depends on your requirements. Use a List for ordered data, a Set for unique elements, and a Map for key-value pairs.
