How to put a Scanner input into an array... for example a couple of numbers

You can get all the doubles with this code:

List<Double> numbers = new ArrayList<Double>();
while (scan.hasNextDouble()) {
    numbers.add(scan.nextDouble());
}

You could try something like this:

public static void main (String[] args)
{
    Scanner input = new Scanner(System.in);
    double[] numbers = new double[5];

    for (int i = 0; i < numbers.length; i++)
    {
        System.out.println("Please enter number");
        numbers[i] = input.nextDouble();
    }
}

It seems pretty basic stuff unless I am misunderstanding you
