> Instead of AbstractBase, make a Numeric class which is contains all numeric utilities.
> ----
> Hello,
> AbstractBase seems to be totally a helper, rather than a base class.
> It's just for providing utility methods to use in a matrix.
> I propose to get rid of it and change it to be a helper, with static methods.
> Then we can use "import static" (a Java 5 feature) to import all
> static methods, and use them in the same way as the current
> implementation.
> Because AbstractBase has no state, and all of its methods has no
> side-effect, so it is not necessary to be in the class hierarchy.
> Regards,
> Chanwit
