What is the difference between collection and List in C#?
What is the difference between collection and List in C#?
List represents a collection where the order of items is important. It also supports methods s.a. Sort and search. Collection is a more general data-structure which makes less assumptions about the data and also supports less methods to manipulate it.
Is a List a type of collection?
Collection types represent different ways to collect data, such as hash tables, queues, stacks, bags, dictionaries, and lists.
What is difference between collections?
The Collection is an interface whereas Collections is a utility class in Java. The Set, List, and Queue are some of the subinterfaces of Collection interface, a Map interface is also part of the Collections Framework, but it doesn’t inherit Collection interface.
How do you declare a collection in C#?
A collection is a class, so you must declare an instance of the class before you can add elements to that collection. If your collection contains elements of only one data type, you can use one of the classes in the System. Collections. Generic namespace.
How many types of collections are there?
Java Collection means a single unit of objects. Java Collection framework provides many interfaces (Set, List, Queue, Deque) and classes (ArrayList, Vector, LinkedList, PriorityQueue, HashSet, LinkedHashSet, TreeSet).

What are different types of collections in net?
Collections. Immutable namespaces to add, remove, and modify either individual elements or a range of elements in a collection. There are two main types of collections; generic collections and non-generic collections. Generic collections are type-safe at compile time.
What is the difference between collection and list in Java?
In Collection, it just stores data with no particular order and can contain duplicate data. Collection is a high-level interface describing Java objects that can contain collections of other objects.
Which is better to use list or collection?
Also, using List is more of a “standard” collection than using Collection directly. Collection is really more designed for those who wish to extend it to create another class, although it technically can be used on it’s own.
What’s the difference between a list and a set?
List and Set interfaces are one of them that are used to group the object. Both interfaces extend the Collection interface. The main difference between List and Set is that Set is unordered and contains different elements, whereas the list is ordered and can contain the same elements in it.
How is a collection similar to a container?
It is similar to the container in the C++ language. The collection is considered as the root interface of the collection framework. It provides several classes and interfaces to represent a group of individual objects as a single unit. The List, Set, and Queue are the main sub-interfaces of the collection interface.
