An Object-Oriented Application

Abstract

The ideas behind object orientation are ones that most people are already familiar with. Most pieces of hardware such as the computers we use are made up of a relatively small number of parts. If these parts are fitted together in the right way you can build a complex piece of equipment very quickly. If you want to build your own PC you can buy a few components such as the mother board, processor, memory, graphics card, and disk drive and plug them together. You do not need to buy individual chips and a soldering iron. If you want to increase the size of your disk drive you just replace it with another drive, you do not attempt to upgrade your existing drive. This idea is widely used to build most pieces of hardware from computers to videos to mobile phones. One of the key ideas behind object orientation is the idea that existing components or objects can be combined to produce complex products.
