    Question Very beginner level code help needed.

    This code should display "incorrect entry" if a entry is not <=100 or =999. I think my code is in the wrong area but can't figure it our where it goes.


     
    import java.util.Scanner;
     
    public class ModifiedTestScoreApp
    {
        public static void main(String[] args)
        {
            // display operational messages
            System.out.println("Please enter test scores that range from 0 to 100.");
            System.out.println("To end the program enter 999.");
     
            System.out.println();  // print a blank line
     
            // initialize variables and create a Scanner object
            double scoreTotal = 0;
            int scoreCount = 0;
            int testScore = 0;
            Scanner sc = new Scanner(System.in);
     
            // get a series of test scores from the user
            while (testScore <= 100)
            {
                // get the input from the user
                System.out.print("Enter score: ");
                testScore = sc.nextInt();
     
                // accumulate score count and score total
                if (testScore <= 100)
                {
                    scoreCount = scoreCount + 1;
                    scoreTotal = scoreTotal + testScore;
                }
                else if (testScore != 999)
                {
                     System.out.println("Invalid entry, not counted");
                }    
            }
     
            // display the score count, score total, and average score
            double averageScore = scoreTotal / scoreCount;
            String message = "\n"
                    + "Score count:   " + scoreCount + "\n"
                    + "Score total:   " + scoreTotal + "\n"
                    + "Average score: " + averageScore + "\n";
            System.out.println(message);
        }
    }

    What does the code do now when it is compiled and executed?
    Show the program's input and output and add some comments saying what the output should be.

    Suggestion: Print out the value of testScore at the end of the error message so you can see what the bad value is.
    If you don't understand my answer, don't ignore it, ask a question.
