Question

I’m not really sure what is wrong with my code…

    public Vector blob (Pixel px)
{
    Vector v = new Vector();

    Point p = new Point(px.getX(), px.getY());
    v.add(p);

    return v;
}

I get the following: warning: [unchecked] unchecked call to add(E) as a member of the raw type Vector

v.add(p);

where E is a type-variable: E extends Object declared in class Vector.

Looking through the API, the add function takes an object as a param which I clearly make the line before, ideas?

Answer 1

Generics!!!. You have to specify the Object type for the contents of the vector.
To remove the warning the vector code should be like this

Vector<Point> v=new Vector<Point>()
