What is state?
Short answer. The data an object knows, like battery or marks.
What is behaviour?
The actions an object does, like charge or study.
State and behaviour
| Entity | State | Behaviour |
|---|---|---|
| Phone | battery | charge |
| Student | marks | study |
Remember
| State: the data it knows |
| Behaviour: the actions it does |
Your phone knows things and does things. Here is how. State is what an object knows. Behaviour is what it does. A phone has battery, and charges. A student has marks, and studies. State is the data. Behaviour is the actions.
