This assignment requires you to write a well documented Java program to calculate the total and average of three scores, the letter grade, and output the results. Your program must do the following: Prompt and read the users first and last name
Prompt and read three integer scores
Calculate the total and average
Determine a letter grade based on the following grading scale - 90-100 A; 80-89.99 B; 70-79.99 C; below 70 F
Use the printf method to output the full name, the three scores, the total, average, and the letter grade, properly formatted and on separate lines.
Within the program include a pledge that this program is solely your work and the IDE used to create/test/execute the program. Please submit the source code/.java file to Blackboard. Attached is a quick reference for the printf method.

The solution is given in the explanation section

Don't forget to add the pledge before submitting it. Also, remember to state the IDE which you are familiar with, I have used the intellij IDEA

Follow through the comments for a detailed explanation of each step

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);

 }

}
