| • | An
object can store information that is a result of |
||||||||||
| prior
operations |
|||||||||||
| • | That
information may determine how the object |
||||||||||
| carries
out operations in the future |
|||||||||||
| • | The
collection of all information held by an object is |
||||||||||
| the
object’s state |

| • | An
object’s state may change over time, but not |
||||||||||
| spontaneously |
|||||||||||
| • | State
changes must be the consequence of operations |
||||||||||
| performed
on the object |
