Arrays

An array is a data structure that contains a group of elements.
Typically these elements are all of the same data type, such as an integer or string.
Arrays are commonly used in computer programs to organize data so that a related set of values can be easily sorted or searched.

Arrays are used to store multiple values in a single variable, instead of declaring separate variables for each value.
String[] cars = {"Volvo", "BMW", "Ford", "Mazda"};
