Following code is the Oval and FilledOval example. However, the Oval’s instance variables are public, which is not optimal. Change those instance variables to private and reimplement any code that depended on the public accessibility of those instance variables.

import java.awt.*;

public class Container {

public int x, y, w, h;

public Container(int x, int y, int w, int h) {

this.x = x; this.y = y; this.w = w; this.h = h;


public void draw(Graphics g) {



public int getWidth() { return w; }

public int getHeight() { return h; }

public Point getTopLeftPoint() { return new Point(x,y); }

//…other methods…


public class Teapot extends Container


public FillTeapot(int x, int y, int w, int h)

{ super(x, y, w, h); }

public void draw(Graphics g)


g.fillOval(x, y, w, h);
