Modify the Test Score application so that it uses Big Decimal arithmetic to
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
