Arrays

• A collection items of any data types.

• Must specify the size, or initialize with data.

// int array of size 3. Empty.
int[] numbers1 = new int[3]; 

// int array of size 3. Contains numbers 11, 22, and 33.
int[] numbers2 = new int[] { 11, 22, 33 }; 

• Refer to any item by a zero-based index:

int[] numbers = new int[] { 11, 22, 33 };
int first = numbers[0];
int last = numbers[2];

• This will generate an 'Index out of range' exception (you are trying to access an index that does not exist):

int[] numbers = new int[] { 11, 22, 33 };
int value = numbers[5];
