Use the getInt and getIntWithinRange methods to validate that each score ranges from 1 through 100 and add code that discards any extra entries at the prompt that asks if you want to enter another score to the application below:

import java.util.Scanner;
import java.text.NumberFormat;

public class TestScoreApp
{
public static void main(String[] args)
{
int scoreTotal = 0;
int scoreCount = 0;
int testScore = 0;
double averageScore = 0;

Scanner sc = new Scanner(System.in);
String choice = "y";
while (!choice.equalsIgnoreCase("n"))
{
// get the input from the user
System.out.print("Enter score: ");
testScore = sc.nextInt();

scoreCount += 1;
scoreTotal += testScore;

averageScore = (double) scoreTotal / (double) scoreCount;

// see if the user wants to enter more test scores
System.out.print("Enter another test score? (y/n): ");
choice = sc.next();
}

NumberFormat number = NumberFormat.getNumberInstance();
number.setMaximumFractionDigits(1);
String message = "\n" +
"Score count: " + scoreCount + "\n"
+ "Score total: " + scoreTotal + "\n"
+ "Average score: " + number.format(averageScore) + "\n";
System.out.println(message);
}
}
