There's also a consideration in that java.util.Arrays carries a number of static primitive[] methods (just as another parallel) for sorting and searching arrays.
We also need to consider that the o.a.c.m.MathUtils/StatUtils do not carry these methods for all primitive types at this time. I'm sure theres alot of room for discussion in both groups as to the best place for such methods and what types to support.
Should primitive[]-->primitive style methods be limited to o.a.c.m.s.StatUtils, or could/should they be made available via o.a.c.m.u.MathUtils or even o.a.c.l.NumberUtils?
Lastly, its the case that Math often delegates to StrictMath for some methods (StictMath being a native Implementation), so there is a precident for "hierarchies" in this case as well.

If we want to be consistent, we could deprecate [lang]'s min/max and point to [math]. This would parallel nicely with c.lang for java.lang and c.math for java.math. It does not seem right to add all primitive types to c.lang.NumberUtils if min/max routines are in c.math.

Subject: Re: [lang] NumberUtils minimum, maximum, and xor
Just to note: we have moved somwhat along these lines in the the commons [math] sandbox component. Currently we have o.a.c.m.stat.StatUtils:
double min(double[] doubleArr) double max(double[] doubleArr)
available there.

I have 2 observations:
(1) Currently, the following methods are in o.a.c.l.NumberUtils
int maximum(int a, int b, int c) long maximum(long a, long b, long c) int minimum(int a, int b, int c) long minimum(long a, long b, long c)
I think it be more flexible to replace them with the following:
int minimum(int[] intArr) int maximum(int[] intArr) long minimum(long[] longArr) long maximum(long[] longArr)
It also may be a good time to add any missing methods such as:
short minimum(short[] shortArr) short maximum(short[] shortArr) float minimum(float[] floatArr) float maximum(float[] floatArr) double minimum(double[] doubleArr) double maximum(double[] doubleArr)
Any thoughts?
(2) After searching for an easy way to xor booleans, and not finding anything, I created a method:
boolean xor(boolean[] boolArr)
Would this be a good addition to NumberUtils?
