Passing an array through a constructor
The values are going into the array but you're doing nothing with them. Probably you want/need to display the values, so use System.out.println public static void main(String[] args) { SArray tester = new SArray(new int[] {23, 17, 5, 90, 12, 44, 38, 84, 77, 3, 66, 55, 1, 19, 37,...

creating a 3d array in python does not create array correctly
You should use labels.append instead of numpy.append Example code - labels = [] for line in lines: lab = [h/100, maxf, title] labels.append(lab) Also this would create the labels list as - [[1,34,u'te],[2,44,u've],[4,43,u'ht]] [1,34,u'te],[2,44,u've],[4,43,u'ht] is not possible in python, these are either three different lists, or they are enclosed by...

Your variable assignments are all wrong. They should be: $range = $_COOKIE["range"]; $longitude = $_COOKIE["longitude"]; $latitude = $_COOKIE["latitude"]; When you try to use a non-numeric string as a number in an arithmetic expression, it's treated as 0.

How to check if data already exists then randomly generate new data from an Array
In my personal opinion, NEVER try to get data from an array within quotes! Always do it outside of quotes; especially in multi-denominational arrays.
