Modify the Test Score application so that it uses Big Decimal arithmetic to calculate the average test score with result rounded to 1 decimal place. Note that because the scoreCount and scoreTotal are int, you don't have to create the Big Decimal object from strings.
import java.util.Scanner;

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;

}

}

// 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: " + round(averageScore,1) + "\n";

System.out.println(message);
