Explanation / Answer

import java.util.Scanner; public class Exercise6_4 { public static void main(String[] args) { double[] scores = new double[10]; double sum = 0.0D; int count = 0; Scanner input = new Scanner(System.in); do { System.out.print("Enter a new score: "); scores[count] = input.nextDouble(); if (scores[count] >= 0.0D) sum += scores[count]; } while (scores[(count++)] >= 0.0D); System.out.println("count is " + count); double average = sum / (count - 1); int numOfAbove = 0; int numOfBelow = 0; for (int i = 0; i = average) numOfAbove++; else numOfBelow++; } System.out.println("Average is " + average); System.out.println("Number of scores above or equal to the average " + numOfAbove); System.out.println("Number of scores below the average " + numOfBelow); } }
