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);
