Dart Sets: Playing with Your Exclusive Party Invitations
In Dart, Sets are like your exclusive VIP party invitations. Now, let's talk about some fun operations, methods, and extensions you can use to manage your special guest list.
1. Operations on a Set: Elegant Moves
Operations are like graceful dance moves at your programming party. Sets come with some cool steps to make managing your guest list a breeze.
Union: Merging Invitations
Imagine merging two exclusive guest lists into one. The union operation in Sets is like combining invitations without duplicates.
Set<String> partyInvitations2 = {'David', 'Eva', 'Alice'}; Set<String> mergedInvitations = partyInvitations1.union(partyInvitations2);
Here, the
union
operation creates a new set with all unique invitations from both lists. It's like blending two exclusive parties into one grand event.Intersection: Mutual Guests
When you want to know which guests are common between two sets, the intersection operation is your friend.
Set<String> partyInvitations1 = {'Alice', 'Bob', 'Charlie'}; Set<String> partyInvitations2 = {'David', 'Eva', 'Alice'}; Set<String> mutualGuests = partyInvitations1.intersection(partyInvitations2);
The
intersection
operation gives you a set of guests who are on both lists. It's like finding the mutual friends who attend both exclusive parties.
2. Set Methods: Smooth Moves
Methods are like smooth dance moves that help you manage your guest list effortlessly.
Adding Guests:
add()
Set<String> partyInvitations = {'Alice', 'Bob', 'Charlie'}; partyInvitations.add('David');
The
add
method gracefully adds a new guest to your set. It ensures uniqueness, making sure no one gets a duplicate invitation.Removing Guests:
remove()
codeSet<String> partyInvitations = {'Alice', 'Bob', 'Charlie'}; partyInvitations.remove('Bob');
With the
remove
method, you can smoothly remove a guest from your exclusive list. It's like an elegant exit without any fuss.
3. Set Extensions: Fancy Footwork
Extensions are like fancy footwork that adds flair to your dance routine. Dart Sets have some cool extensions to spice up your programming party.
Sorting:
toSortedList()
Set<int> numbers = {3, 1, 4, 1, 5, 9, 2, 6, 5, 3, 5}; List<int> sortedNumbers = numbers.toSortedList();
The
toSortedList
extension arranges your set in ascending order. It's like organizing your playlist for a smooth and harmonious party vibe.Reversing:
toReversedList()
Set<String> partyInvitations = {'Alice', 'Bob', 'Charlie'}; List<String> reversedGuests = partyInvitations.toReversedList();
Using
toReversedList
, you can create a new list with your guests in reverse order. It's like changing the direction of your party vibes for a unique experience.
