Answer 1

Explanation:

attributed by the way it is a good time

Answer 2

Answer:

objects consist of attributes, states, and behavior, if you define attributes to mean non-changing characteristics of an instance. As a matter of fact, it is important to make this distinction, because there exist objects which contain only attributes, (in your sense,) and no state; they are called immutable and they are very useful in programming.

This three-part definition is indeed represented in programming languages, for example using the final keyword in Java or the readonly keyword in C# to denote instance data which may not change throughout the lifetime of the instance.

I have to add, though, that non-changing instance data are usually not called attributes. We tend to speak of them as 'final' or 'readonly' or 'constant data' depending on which language we are using. The proper term for them would be 'invariants', but then this word is not frequently used in this sense; it is more often used for other things.
