How to implement infinity in Java?

Question

Does Java have anything to represent infinity for every numerical data type? How is it implemented such that I can do mathematical operations with it?

E.g.

Answer 1

I'm not sure that Java has infinity for every numerical type but for some numerical data types the answer is positive:

Float.POSITIVE_INFINITY
Float.NEGATIVE_INFINITY

or

Double.POSITIVE_INFINITY
Double.NEGATIVE_INFINITY
