How to Find Array Names in a Set

Hello,

I have a series of arrays that I inserted into a HashSet. Now I want to
find out whether a particular array is contained in the set; how do I do
that? Here is what the code looks like:

double array1 = {1.0, 2.0, 3.0, ...};
double array2 = {1.0, 2.0, 3.0, ...};
double array3 = {1.0, 2.0, 3.0, ...};
.
.
.

Set<double[]> hs = new HashSet<double[]>();
hs.add(array1);
hs.add(array2);
hs.add(array3);
.
.
.

// Retrieve name of array, say arrayX, from a text field.

// ArrayX will not be found because arrayX is a String and Array1, etc, are
array objects.
if (hs.contains(arrayX)) { // How do I test for arrayX?
...
}


.
