Why can't I compiled this Java program in Jgrasp?

import java.util.*; public class TotalArea { /** Main method */ public static void main(String[] args) { // Declare circleArray CircleWithPrivateDataFields[] circleArray; // Create circleArray circleArray = createCircleArray(); // Print circleArray and total areas of the circles printCircleArray(circleArray); }

/** Create an array of Circle objects */

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; }

/** Print an array of circles and their total area */ public static void printCircleArray(CircleWithPrivateDataFields[] circleArray) { System.out.printf("%-30s%-15s ", "Radius", "Area"); for (int i = 0; i < circleArray.length; i++) { System.out.printf("%-30f%-15f ", circleArray[i].getRadius(), circleArray[i].getArea()); } System.out.println("-"); // Compute and display the result System.out.printf("%-30s%-15f ", "The total area of circles is", sum(circleArray) ); }

/** Add circle areas */ public static double sum(CircleWithPrivateDataFields[] circleArray) { // Initialize sum double sum = 0; // Add areas to sum for (int i = 0; i < circleArray.length; i++) sum += circleArray[i].getArea(); return sum; } }

The error is:
