编写一个程序，读人个数不确定的考试分数，并且判断有多少个分数是大于或等于平均分，多少个分数是低于平均分的。输人一个负数表示输入的结束。假设最高分为100。
Write a program that reads an unspecified number of scores and determines how many scores are above or equal to the average and how many scores are below the average. Enter a negative number to signify the end of the input. Assume that the maximum number of scores is 100.

import java.util.Scanner;
public class Ans7_4_page236 {
public static void main(String[] args) {
double[] scoreList = new double[100];
Scanner input = new Scanner(System.in);
System.out.print("Enter scores: (negative number signifies end): ");
int count= 0;double score;
do {
score = input.nextDouble();
scoreList[count] = score;
count ;
}while (score >= 0);
double average,sum = 0;
for (int i = 0; i < count-1; i )
sum = scoreList[i];
average = sum / (count - 1);
System.out.println("Average of scores: " average);
int minAverge = 0;
int maxAverge = 0;
for (int i = 0; i < count-1; i ) {
if (scoreList[i] >= average)
minAverge ;
else
maxAverge ;
}
System.out.println("Number of scores above or equal to average: " minAverge
"n" "Number of scores below average: " (maxAverge));
}
}
