Array Definitions
Array  A collection of homogenous elements, given a single
name
Length  A variable associated with the array that contains the
number of locations allocated to the array
Subscript (or index)  A variable or constant used to access a
position in the array:  The first array element always has
subscript 0, the second has subscript 1, and the last has
subscript length-1
When allocated, the elements are automatically initialized to
the default value of the data type: 0 for primitive numeric
types, false for boolean types, or null for  references
types.
