Finding Min and Max of Circle Radius

Alright so all of the methods word except the minMax method, this is a file that takes information from my CircleWithPrivateDataFields.java If you need any of the code from that you can let me know and I can reedit this file with the appropriate files.

This is my error: double cannot be converted to CircleWithPrivateDataFields

what will I have to do for this to work, I know I'm very close, but I'm not sure where to go from here.

Remember it's the minMax method that only needs work.

Thanks in advance!

 public class TotalArea {
 public static void main(String[] args) {
  //Declare circle array
  CircleWithPrivateDataFields[] circleArray;

  //Create circleArray
  circleArray = createCircleArray();

  printCircleArray(circleArray);

  minMax(circleArray);        
 }

public static CircleWithPrivateDataFields[] createCircleArray() {
  CircleWithPrivateDataFields[] circleArray = new CircleWithPrivateDataFields[5];

  for (int i=0; i < circleArray.length; i++) {
     circleArray[i] = new CircleWithPrivateDataFields(Math.random() * 100);
  }
     //Return circle array
  return circleArray;
}//end createCircleArray method

/*

  takes the array of circles and determines the 
  smallest and largest circles in the array and prints out their information.

*/

public static void minMax(CircleWithPrivateDataFields[] circleArray) {
System.out.println();
double max;

  for (int i=0; i<circleArray.length; i++) {
     if(circleArray[i].getRadius() > 0) {
        circleArray[i] = max;
     }

  }
}



   //Add circle areas
     public static double sum(CircleWithPrivateDataFields[] circleArray) {
        //Initalize sum
  double sum = 0;

        //Add areas to sum
  for (int i=0; i<circleArray.length; i++)
     sum += circleArray[i].getArea();

  return sum;
 }
}

You are adding max (a double) to circleArray which is an array of CircleWithPrivateDataFields.

You have to make sure that circleArray is an array of double or that the CircleWithPrivateDataFields class extends Double.
