The current values of an object's data at a moment in time.

What is State?

An object's state is the current values of its data. A light switch object might be in the "on" state or the "off" state. Calling methods usually changes the state.

var lamp = new Lamp();  // IsOn = false
lamp.TurnOn();          // IsOn = true: the state changed
