Is Java.awt.geom suitable for discrete calculations?

Question

The package java.awt.geom allows testing if a point lies within a rectangle and similar questions. In particular I need to know if a rectangle is intersected by a line. All involved values are integers.

However, it appears we cannot have those calculations use integers instead of floating point. As I need a completely consistent and reproducible result (its factual accuracy is not as important, actually), I am worried this might be a bad approach. The program will be deployed on Windows, Linux and Android platform, and I do not have full control over the machines.

I have implemented the required algorithm myself (using pure integer arithmetic), and it suffices all my needs. Yet, if possible, I would like to use the preprovided package. Is there some sort of guarantee on its consistency?

Answer 1

Yet, if possible, I would like to use the preprovided package.

It is unlikely the J2SE classes will be available in Android, so stick with your own custom rolled solution.
