Explanation:
/*This is a Java program to calculate the total and average of three scores, the letter grade, and output the results*/
// Importing the Scanner class to receive user input
import java.util.Scanner;
class Main {
public static void main(String[] args) {
//Make an object of the scaner class
Scanner in = new Scanner(System.in);
//Prompt and receive user first and last name;
System.out.println("Please enter your first name");
String First_name = in.next();
System.out.println("Please enter your Last name");
String Last_name = in.next();
//Prompt and receive The three integer scores;
System.out.println("Please enter score for course one");
int courseOneScore = in.nextInt();
System.out.println("Please enter score for course two");
int courseTwoScore = in.nextInt();
System.out.println("Please enter score for course three");
int courseThreeScore = in.nextInt();
//Calculating the total scores and average
int totalScores = courseOneScore+courseTwoScore+courseThreeScore;
double averageScore = totalScores/3;
/*Use if..Else statements to Determine a letter grade based on the following grading scale - 90-100 A; 80-89.99 B; 70-79.99 C; below 70 F */
char letterGrade;
if(averageScore>=90){
letterGrade = 'A';
}
else if(averageScore>=80 && averageScore<=89.99){
letterGrade = 'B';
}
else if(averageScore>=70 && averageScore<=79.99){
letterGrade = 'C';
}
else{
letterGrade ='F';
}
//Printing out the required messages
System.out.printf("Name: %s %s\n", First_name, Last_name);
System.out.printf("scores: %d %d %d: \n", courseOneScore, courseTwoScore, courseThreeScore);
System.out.printf("Total and Average Score is: %d %.2f: \n", totalScores, averageScore);
System.out.printf("Letter Grade: %C: \n", letterGrade);
// System.out.printf("Total: %-10.2f: ", dblTotal);
}
}
