Defining Object Model

In order to create a model (class) for an object, we must define its 2 major components:

• Attributes or State (variables)
• Behavior (Methods/Functions)

Attributes or State

Current characteristics of the specified. These attributes may change over time.

Behavior

• possible actions of the object is able to do.
  • actions to change it’s own or other’s state
  • actions to tell it’s own state
  • actions to do both

Anthropomorphic

• Each object is smart or expert enough for its own task
• needs commands from another object to perform their expertise

Abstraction

• “black box”
• specific details are hidden and only general details are visible
