I'm having trouble working these last few kinks out my progarm. It would be greatly appreciated if you can help me out from here.

           double area =(Math.PI)*(Math.pow(aRadius, 2));

          myCircle.Aarea(aRadius);

          System.exit(0);
       }
   }

The application prompts the user to enter the radius of a circle.
• If the user enters invalid data, the application displays an appropriate error message
and prompts the user again until the user enters valid data.
• When the user enters a valid radius, the application calculates and displays the
circumference and area of the circle to the nearest 2 decimal places.
• The application prompts the user to continue.
• When the user chooses not to continue, the application displays a goodbye message
that indicates the number of Circle objects that were created by the application.

so, what exactly is it you are having difficulties with?
