What properties characterize objects in object-oriented programming?

Objects in object-oriented programming are characterized by the following main properties:

• State — a set of field (attribute) values that describe the current data of the object.
• Behavior — methods or functions that the object can perform, defining its actions.
• Identity — the uniqueness of the object, allowing it to be distinguished from other objects, even if their state is the same.

For example, an "Automobile" object may have a state: color, brand, speed; behavior: drive, brake, turn; and a unique identifier that distinguishes it from other cars.
