to compile, I changed
Graph graph
to JPanel graph

compiled/ran, error, opened java console which showed
NumberFormatException, line 574
which is this line
carnum = Integer.parseInt(getParameter("carnum"));

changed to a hard-coded value
carnum = Integer.parseInt("10");

and the applet started OK

I have made the corrections that you mentioned above but
I am still getting an error as below:

panel = new GraphPanel(this);
Its showing
constructor GraphPanel in class project.GraphPanel cannot be applied to given types;
reason:actual argument project.Graph cannot be converted to javax.swing.JPanel by method invocation conversion
Its asking to create constructor GraphPanel(project.Graph) in project.GraphPanel
How to solve this?
It is sorta covered in the JavaRanch Style Guide.
