can we define same functions for the two or more different objects of different class

[saneha]

) it is necessary for any object/entity that it has some attributes , behavior or both????

2) can we show some entities without attributes or their functions in some scenarios/cases ?????

3) can we define same functions for the two or more different objects of different classes.?

It is necessary that all objects have some attributes as well as behaviour.
2. In real life every object has its attributes and behaviour, so every entity has attributes and functions.
3. Yes we can define same functions for more than two different objects of different classes.
