An array is a collection of elements stored in a contiguous block of memory.

Each element in the array must be of the same data type and be differentiated by the index. The index of each of the arrays is 0.

Two steps to create an array: 1, declare a reference to an array, 2, initialize the arrays using the New keyword, and specify the size of the array.

For example:

Int[] age; 1

Int[] age = new INT[5]; 2

1 means that an array with the name of age is declared, and 2 indicates that the array is initialized, and the size of the array is specified as 5.
