What is an Object?
An object is ►
Something tangible (Ali, Car)
►
Something that can be apprehendedintellectually (Time, Date)
… What is an Object?
An object has ►
State (attributes)
►
Well-defined behaviour (operations)
►
Unique identity
Example – Car is a Tangible Object
►
State (attributes)
- Color- Model
►
behaviour (operations)
- Accelerate
- Start Car
- Change Gear
►
Identity
- Its registration number
Example – Time is an Object
Apprehended Intellectually
►
State (attributes)
- Hours
- Seconds
- Minutes
►
behaviour (operations)
- Set Hours
- Set Seconds
- Set Minutes
►
Identity
- Would have a unique ID in the model
