public class DebugFour2

{

   public static void main(String args[])

   {

       double radius = 12.6;

       System.out.println("Circle statistics");

       double area = Math.PI * radius * radius;

       System.out.println("area is " + area);

       double diameter = 2 * radius;

       System.out.println("diameter is " + diameter);

   }

}

First off, I added a double quote to "diameter is ". You didn't have the second double quote. Also, I changed the calculation for diameter. You had 2 - radius. The diameter is actually 2 * radius.

I hope this helps!
