Java program to convert a list to an array Create a List object. Add elements to it. Create an empty array with size of the created ArrayList. Convert the list to an array using the toArray () method, bypassing the above-created array as an argument to it. Print the contents of the array.

A simple way to create an array from data or simple Python data structures like a list is to use the **array() function**. The example below creates a Python list of 3 floating point values, then creates an ndarray from the list and access the arrays’ shape and data type.

Array programming. In computer science, array programming languages (also known as vector or multidimensional languages) generalize operations on scalars to apply transparently to vectors, matrices, and higher-dimensional arrays. Array programming primitives concisely express broad ideas about data manipulation .

The term array is often used to mean **array data type**, a kind of data type provided by most high-level programming languages that consists of a collection of values or variables that can be selected by one or more indices computed at run-time.
