how to convert double array to collection?

Question

I have two arrays

   double arr[]=data.attributeToDoubleArray(4);
   double arr0[]=data.attributeToDoubleArray(0);

To calculate p value in common apache it has been documented as follows :

 public double anovaPValue(Collection<double[]> categoryData)
               throws NullArgumentException,
                      DimensionMismatchException,
                      ConvergenceException,
                      MaxCountExceededException

       Computes the ANOVA P-value for a collection of double[] arrays.
       Preconditions:

        The categoryData Collection must contain double[] arrays.
        There must be at least two double[] arrays in the categoryData collection and each of these arrays must contain at least two values.

How can I convert my two arrays in collection so that I can use the above function ?

`Arrays.asList(arr, arr0)` is probably the easiest way to make a `Collection` — 4castle, Jul 13 '17 at 04:14

you can try this:

double arr[]=data.attributeToDoubleArray(4);
double arr0[]=data.attributeToDoubleArray(0);

List<double[]> newArr = Arrays.asList(arr, arr0);
