In Apex, arrays are ordered collections of elements, and they are used to store multiple values of the same data type. The size of an array is fixed when it is declared, meaning you need to specify the number of elements it can hold. Apex supports one-dimensional arrays.

Here's a basic example of declaring and using an array in Apex:

Integer[] numbers = new Integer[5];

numbers[0] = 1;
numbers[1] = 3;
numbers[2] = 5;
numbers[3] = 7;
numbers[4] = 9;

System.debug(numbers);

Output: (1, 3, 5, 7, 9)
