Java Ellipse drawing

Question

I am writing a shape class for a circle its supposed to output the shape plus its dimensions. i am trying to do the same thing i did for my square and rectangle class but its not working. i will post here my main method, my rectangle class as a reference for what works and lastly my circle class which works but when i try to use it in the main method it gives me the error "The method add(component) in the type Container is not applicable for the arguments (Ellipse2D.Double)" on the line where it says frame3.add(myCircle);

Answer 1

Here you are attempting to add a Shape to the frame :

Ellipse2D.Double myCircle = new Ellipse2D.Double(50,50,width,height);
//...
frame3.add(myCircle);

You are supposed to add a Component , not a Shape , so you probably wanted to write :

Circle myCircle = new Circle(height, width);
//...
frame3.add(myCircle);
