Get the minimum and maximum of an Array

Demo Code

/*//from   ww  w .  j  av  a2s . c o m
 * Get the minimum and maximum of an Array, if the array is to
 * big it has to do it recursively because funcitons like Math.min don't
 * take an infinite amount of arguments and that could have been inteligently
 * solved by taking a array instead. But we have to live with is and just accept
 * that somethings aren't perfect.
