Do a getBounds on the sphere, and make sure the at the auto compute bounds is set to 
true.  The bounds should be passed to a bounding sphere and this has a method 
geCenter.  That should work.

com.sun.j3d.utils.geometry.Sphere sphere = new com.sun.j3d.utils.geometry.Sphere(10.0);
sphere.setAutoComputeBounds(true);
javax.media.j3d.BoundingSphere bSphere = sphere.getBounds();
javax.vecmath.Point3d center;
bSphere.getCenter( center );

Something like that should work.

I have spheres and cylinders in my scene. After transformation, how can
I get the center points of these objects. Alternatively, how do I get
the new bounding box/spheres for each objects?

Thank you,

Kovalan
