What is the difference between List and array types?

The main difference between these two data types is the operation you can perform on them. Also lists are containers for elements having differing data types but arrays are used as containers for elements of the same data type.

What is difference between List and ArrayList in C#?

ArrayList simply stores object references. As a generic collection, List implements the generic IEnumerable interface and can be used easily in LINQ (without requiring any Cast or OfType call). ArrayList belongs to the days that C# didn’t have generics. It’s deprecated in favor of List .

Is Java an ArrayList?

ArrayList is a part of collection framework and is present in java. util package. It provides us with dynamic arrays in Java.

Is ArrayList faster than array?

The capacity of an Array is fixed. Whereas ArrayList can increase and decrease size dynamically. Whereas ArrayList can hold item of different types. An array is faster and that is because ArrayList uses a fixed amount of array.

What is the difference between ArrayList and Java?

1) First and Major difference between Array and ArrayList in Java is that Array is a fixed-length data structure while ArrayList is a variable-length Collection class. You can not change the length of Array once created in Java but ArrayList re-size itself when gets full depending upon the capacity and load factor.

What is difference between list and ArrayList in Kotlin?

Memory representation and operations logic of lists are defined in concrete implementation, e.g. indexing in a LinkedList goes through the links and takes O(n) time whereas ArrayList stores its items in a dynamically allocated array.

Is a Python list an array?

While lists and arrays are superficially similar—they are both multi-element data structures—they behave quite differently in a number of circumstances. First of all, lists are part of the core Python programming language; arrays are a part of the numerical computing package NumPy.

What is the difference between list and array in asp net?

A list is a data structure that supports several operations. An array is a collection of homogenous parts, while a list consists of heterogeneous elements. Array memory is static and continuous. List memory is dynamic and random.

What is the difference between list and dictionary in C#?

The Dictionary maps a key to a value and cannot have duplicate keys, whereas a list just contains a collection of values. Also, Lists allow duplicate items and support linear traversal.
