What is the difference between Set and List?
Set is a collection that refrains from duplicate values and doesn't promise any order of its elements. List, being more agreeable, tolerates duplicates and thoughtfully retains the insertion order.
For the HashSet, the duplicate "apple" simply does not exist. The ArrayList welcomes both "apple" entries and keeps them in their order.
A taste of List and Set
Performance implications for culinary delight
Whip up efficient applications with List and Set by understanding their performance nuances. The LinkedList operates like a sushi conveyor belt, quick at adding and removing dishes in the middle. An ArrayList behaves like a DIY salad bar where access to all the ingredients is direct. On the other hand, the HashSet is like a quick counter serving unique dishes in no time.
Select your kitchen tool: List or Set
Are you planning a party with a guest list? If you need to avoid duplicate guests and sequence doesn't matter, Set is your bouncer at the door. But, if the party requires a specific play order for party games, get a List.
When HashSet, LinkedHashSet, and TreeSet walk into a kitchen
Here are some utilities in your kitchen. LinkedHashSet is a magical pot, keeping the insertion order while ensuring no duplicate ingredients. A TreeSet, is your sous chef sorting out your ingredients as per their recipe order or as you specify.

LinkedHashSet: The balancing act between List and Set
When you need uniqueness and order both, LinkedHashSet has got your back. This unique collection is like a library which ensures all books are different (uniqueness) and yet they are well-arranged for quick access (order).
TreeSet: Sorted and lean
A TreeSet not only keeps things neat but also sorts them for you. It’s like having a robotic housekeeper that keeps everything clean and organized.
ArrayList vs LinkedList: A friendly feud
Imagine an ArrayList as a vending machine with direct access to all items (random access), while a LinkedList is more like a magician's hat, where one needs to go through each item (sequential access) to get to the desired one.
