How to fix Circle.java:18: variable radius might not have been initialized error

[blknmld69]

I keep getting the error: Circle.java:18: variable radius might not have been initialized

 import java.util.Scanner;
   import java.io.*; 
 
    public class Circle
   {
       public static void main(String args[]) 
      {
         double radius, area;
         double pi = 3.14159;
 
         System.out.println("Enter radius >= 0 ");
 
 
         System.out.println("Circles radius = " + radius);
         area = pi * radius * radius;
         System.out.println("Circles Area = " + area);
      }
   }

The error is telling you exactly what is wrong.

You have declared a variable called "radius", but you have never assigned a value to it. Therefore you are trying to use an uninitialized variable.

You print the prompt to enter a radius but you never use a Scanner to get the input.
