An Object-Oriented World

Example: Watching TV
- From “Learn Java Now”, Stephen R. Davis, Microsoft Press
A TV is a physical object
- A TV is a well-defined concept with well-defined boundaries
- The concept of TV is universally understood
A TV remote control provides user interface
- No other interface is needed
- No additional knowledge of TV internals is needed
A TV “works” right out of the box
- Robust, fully operational, not expected to fail
- Its relations/ attachments to the world are fully documented
