An ArrayList wrapper with a fixed size.


list is a null reference (Nothing in Visual Basic).

This wrapper can be used to prevent additions to and deletions from the original ArrayList. The elements can still be modified or replaced.

A collection with a fixed size is simply a collection with a wrapper that prevents adding and removing elements; therefore, if changes are made to the underlying collection, including the addition or removal of elements, the fixed-size collection reflects those changes.

This method is an O(1) operation.

The following code example shows how to create a fixed-size wrapper around an ArrayList.
