getPerimeter of a rectangle

Code java:

---

public class Rectangle {
 
 
 
	public static void main(String[] args) {
 
 
	}
 
	 public Rectangle(int x, int y, int height, int width)
 
	 {
 
		 Rectangle r = new Rectangle(x, y, height, width);
 
 
	 }
	 public int getPerimeter()
	 {
 
 
		return p;
 
	 }

Did you have a question?

x and y are the co-ordinates of upper left corner and height and width are given as above. It suppose to return perimeter of the rectangle. I could n't find where to start? I know the formula to get Perimeter = 2(height + width) but what do I do with it's coordinate x and y? It should be done with methods so I layout the code structure as you see above. Please give me some ideas on this.

--- Update ---

Yes, I was typing it. It should be up by now.

The x,y are the location of the rectangle. They are not used in computing the perimeter.

I think this is what you're looking for

I got ' r can't be resolved error'; how should I construct Rectangle r?

The formula in your post#3 should work.
