Write the method

double[] newArray(ArrayList<Double> list)

which takes a list of floats as its parameter. 
The method creates and returns a floating point array with the same elements in the same order as the list.

Example method call:

public static void main(String[] args){
    ArrayList<Double> test = new ArrayList<>();
    test.add(1.0);
    test.add(3.0);
    test.add(2.75);

    double[] array = newArray(test);
    System.out.println("Array: " + Arrays.toString(array));
}

Program outputs:
Array: [1.0, 3.0, 2.75]

        // for list - need to get element using idx
        for (int i = 0; i < list.size(); i++) {
            array[i] = list.get(i);
        }
