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 a beginner in Java... I found another implementation for the infinity in the Java documentation, for the boolean and double types. https://docs.oracle.com/javase/specs/jls/se7/html/jls-4.html#jls-4.2.3

Positive zero and negative zero compare equal; thus the result of the expression 0.0==-0.0 is true and the result of 0.0>-0.0 is false. But other operations can distinguish positive and negative zero; for example, 1.0/0.0 has the value positive infinity, while the value of 1.0/-0.0 is negative infinity.

It looks ugly, but it works.

public class Main {

    public static void main(String[] args) {
        System.out.println(1.0/0.0);
        System.out.println(-1.0/0.0);
    }

}
