The PAC software design pattern to create a user interface for a 9-page book. The interface must have four buttons to allow the user to render the first page, last, previous, and the next page of the book. The rendering behavior has access to an array of book pages. The table that follows lists the behavior associated with each one of the four buttons. An abstraction of the 9-page book is provided by the structure below where the upper row refers to page numbers and the bottom row indicates the contents of each page. For instance, the left most cell of this two-dimensional structure refers to page number 1 (first) which contains the string Page1 and the right most cell refers to page number 9 (last) which contains the string Page9.

In each pages, must say "This is page ____".
