Is Abstraction an absolute property?

[anyonebutangel]

TL;DR

what is an absolute property and why is Abstraction in java considered an absolute property?

I came across this line in my java textbook-"Abstraction is the absolute property of a class".i want to know what does absolute property exactly mean and why it is considered an absolute property?Also how does it effect(or is useful) when we practically do programming?

Is it because you can call a class an abstraction; it is an example of an abstraction itself? And that never changes. This is just a guess.
