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!

try this:

go tos official website.

click on your profile pic at the top right of the screen and click 'edit profile'.

click on "preferences" and press "year of birth".

and then just maybe try to reset whatever error made before by typing in the correct age details again. hope this !
