There are two ways of doing this. If you can determine a mathematical function, use that. Otherwise, try this:

final double[] SPEED = {double1, double2, double3...};

The reason your compiler didn't like the line you posted is because of syntax. It should have looked like this:

double[] SPEED = new double[SIZE];

I don't recommend using an ArrayList as they use a lot more memory than you need and they require objects, not primitives.
