In object-oriented programming, the key idea is to split code into several small, manageable parts or objects. Each object has its own identity, data (or attributes), and logic (or behavior). For example, consider modeling an elephant in software.
Attributes are the properties of the object. For example, in the case of the elephant, things such as these:
- Weight
- Color
- Type

The collection of all these attributes describes the current state of an object. The state of one object is generally independent of another. Behavior is things that the object can do; in the case of an elephant, it can trumpet. Behavior is the object's interface with the outside world. The individual constructs (or functions) by which you can ...
