list and arraylist in java

Why we use list instead of ArrayList in Java?
ArrayList offers more functionality and flexibility, but using List can help you create a more generalized program.
In this example, we've created a List object using the ArrayList class.
We then added the string 'Hello' to the list and printed the first item in the list, which outputs 'Hello'._{6 nov. 2023}
Key Difference Between ArrayList vs LinkedList
ArrayList uses an array, which allows for fast random access but slow insertion and deletion.
While LinkedList uses a doubly linked list, which allows for fast insertion and deletion but slow random access.
Also one of the major difference lies in the access time.

What is list of () in Java?

List. of() is a factory method introduced in Java 9 that creates an immutable list containing the specified elements.
Here are some key points to note: Immutability: The resulting list is immutable, meaning its size and elements cannot be modified after creation.

What's the difference between list and ArrayList in Java?

The List refers to a collection of various elements in a sequence, in which every element is basically an object.
Also, we can access these elements by their positions (index).
On the other hand, an ArrayList creates an array (dynamic) of the objects that can easily reduce or increase in size as and when required.

List interface is used to create a list of elements(objects) that are associated with their index numbers. ArrayList class is used to create a dynamic array that contains objects. List interface creates a collection of elements that are stored in a sequence and they are identified and accessed using the index.
