Question

我们应该创建一个循环，重复学生所需的次数。在设置一个不在代码中的预定计数上运行的循环时，我完全迷失了。

我们必须创建循环。我甚至都不知道从哪里开始，因为书中没有任何内容可以让我看到这种情况。

感谢任何帮助，让我朝着正确的方向前进。

import java.util.*;
public class TestScoreStatistics
{
   public static void main (String args[])
   {
      int score;
      int total = 0;
      int count = 0;
      int highest;
      int lowest;
      final int QUIT = 999;
      final int MIN = 0;
      final int MAX = 100;
      Scanner input = new Scanner(System.in);

      System.out.print("How many scores would you like to enter >> ");

      enterCount  = input.nextInt();
      System.out.print("Enter a score >> ");
      score = input.nextInt();

     //Create a while statement that will loop for the amount entered
      while( count != QUIT )
      {
          }

         System.out.print("Enter another score >> ");
         score = input.nextInt();
      }

      System.out.println(count + " scores were entered");
      System.out.println("Highest was " + highest);
      System.out.println("Lowest was " + lowest);
      System.out.println("Average was " + (total * 1.0 / count));
   }
}

因此。您似乎要求输入分数，直到用户输入了与enterCount：

中定义的分数一样多的分数

List<Integer> scores = new ArrayList<Integer>(); 
while( count < enterCount ) {
    System.out.print("Enter another score >> ");
    score = input.nextInt();
    scores.add(score);
    count++;
}

您可能需要定义某种类型的List，其中包含分数。
