Abstract Functions in ArrayClassList

Here is the link for a program that shows how to tap the abstract functions of the ArrayListClass:

Array-Based Lists (Chapter 3)

Array-Based Lists

http://www.2shared.com/file/EBAxGx23/ArrayBasedList.html

This program would ask the user for 8 integers. Then, it will ask a position to be deleted and display the smallest number.

Inheritance Box

The link for Inheritance Box:

http://www.2shared.com/file/dd7MqR6Z/Inheritance_Box.html

This program would ask the user for the length, width and depth of a box, and calculate its volume. Updated with try/catch block and do while loop

Below is the encoded version of the program.
