Question

Is it possible to draw a polyline by passing the method an array list of Point values? something like this:

 ArrayList<Point> projectilePoints=new ArrayList<Point>();
    Projectile p = new Projectile(11, 17, 73, 37);

    for (int i = 0; i < 11; i++) {
        Point point = p.getPositionAt(i);
        projectilePoints.add(point);
    }
    g.drawPolyline(projectilePoints, projectilePoints, 11);

What is the correct way to pass in the parameters of x and y points for the polyline?

Answer 1

No, there is no such method takes Arraylist of Point reference parameter. The Syntax is,

Graphics.drawPolyline(int[] xPoints, int[] yPoints, int nPoints)
