What does a programmer mean when he refers to the state of an object?
| A4: || |
In the world of object oriented programming (OOP), everything is viewed as an object. You, for example, can be viewed as an object. If you were meeting a stranger at the airport, how would you describe yourself so he would recognize you? You might say: "I'm 6' tall, weigh 200 pounds , have blonde hair, and I'll be wearing a blue suit with a yellow tie." Notice how you use properties to describe yourself. In other words, you hair color and clothing help define your current state. Several months from now you could be 20 pounds lighter, have red hair, and wear different clothes, thus changing your state. Your state, therefore, is defined by the current values of the properties that define you as an object.
