A one-dimensional array is a collection of
objects in which the objects are stored and retrieved via an integer
index. Each object in an array is called an
element of that
array. In Smalltalk, the first element is indexed by 1; hence,
Smalltalk is said to have 1-based arrays.
The following, for example, is a diagram of a one-dimensional array with integer elements:
1 2 3 4 <-- Index *------*------*------*------* | 570 | 720 | 640 | 720 | *------*------*------*------*
