Java Porting of the Miniball.h code of Bernd Gaertner. Look at http://www.inf.ethz.ch/personal/gaertner/miniball.html
and related work at http://www.inf.ethz.ch/personal/gaertner/texts/own_work/esa99_final.pdf
for reading about the algorithm and the implementation of it.
If interested in Bounding Sphere algorithms read also published work of Emo Welzl "Smallest enclosing disks (balls and Ellipsoid)" and the work of Jack Ritter on "Efficient Bounding Spheres" at
