Description: An array list is a data structure that allows storing a collection of elements in a contiguous sequence of memory. In programming languages, this resizable array implementation enables developers to efficiently add, remove, and access elements. Unlike static arrays, which have a fixed size, resizable arrays can grow or shrink as needed, providing great flexibility in data management. This feature is particularly useful in situations where the number of elements is not known in advance. Arrays are dynamic, meaning they can be modified at runtime, allowing operations such as inserting and deleting elements without the need to create a new array. Additionally, arrays are heterogeneous, meaning they can contain elements of different data types, which increases their versatility. In summary, array lists are fundamental in modern programming as they offer an efficient and flexible way to handle collections of data.
