Storing Point2D.Double objects in an ArrayList.

[Lord Felix]

Im not very sure on how to store the (x,y) coordinates of the Point2D.Double object into an ArrayList so that I could access them later. I have looked through the Java classes on Point2D.Double, but have only found its constructors and methods and not on how the coordinates can be stored in an ArrayList. I have not much of a lead on this but here's at what I have so far:

public class IrregularPolygon
{
	private ArrayList myPolygon;
	
	public IrregularPolygon() 
	{
	}

	public void add(Point2D.Double aPoint) 
	{
		myPolygon.add(aPoint);
	}

	public void draw() 
	{   
		DrawingTool pencil;
		SketchPad paper;
		paper = new SketchPad(450,450);
		pencil = new DrawingTool(paper);
		
		
	}

	public double perimeter() 
	{   
		double perim = 0;
		
		return perim;
	}

	public double area() 
	{   
		int area = 0;
		
		return area;
	}

}

class IPTester
{
	public static void main(String[] args)
	{
		IrregularPolygon poly = new IrregularPolygon();
	
		poly.add(Point2D.Double(50.0, 50.0));
	}
}

Thanks in advance :)
