Overview
Array instances are objects. They are dynamically created, they can be assigned to a variable of type Object and all methods of class Object may be invoked on an array.
An array instance contains a number of variables, called array components that have no names, and can be referenced instead by array access expressions that use non-negative integer indices.
If the number of components of an array is zero, the array is said to be empty. If the array has n components, then it is said that the array has the length n. In this case, its components are referenced with zero-based indices from 0 to n-1.
