Question

Write the class "Tests". Ensure that it stores a student’s first name, last name, all five test scores, the average of those 5 tests’ scores and their final letter grade. (Use an array to store all test scores.)

Answer 1

Answer:

The following assumption will be made for this assignment;

• If average score is greater than 75, the letter grade is A

• If average score is between 66 and 75, the letter grade is B

• If average score is between 56 and 65, the letter grade is C

• If average score is between 46 and 55, the letter grade is D
• If average score is between 40 and 45, the letter grade is E
• If average score is lesser than 40, the letter grade is F

The program is written in Java and it uses comments to explain difficult lines. The program is as follows

import java.util.*;

public class Tests

{

public static void main(String [] args)

{

 //Declare variables

 Scanner input = new Scanner(System.in);

 String firstname, lastname;

 //Prompt user for name

 System.out.print("Enter Lastname: ");

 lastname = input.next();

 System.out.print("Enter Firstname: ");

 firstname = input.next();

 char grade;

 //Declare Array

 int[] Scores = new int[5];

 //Initialize total scores to 0

 int total = 0;  

  //Decalare Average

  double   average;

 //Prompt user for scores

 for(int i =0;i<5;i++)

 {

  System.out.print("Enter Score "+(i+1)+": ");

  Scores[i] = input.nextInt();

  //Calculate Total Scores

  total+=Scores[i];

 }

 //Calculate Average

 average = total/5.0;

 //Get Letter Grade

 if(average>75)

 {

 grade = 'A';

 }

 else if(average>65)

 {

 grade = 'B';

 }

 else if(average>55)

 {

 grade = 'C';

 }

 else if(average>45)

 {

 grade = 'D';

 }

 else if(average>40)

 {

 grade = 'E';

 }

 else

 {

 grade = 'F';

 }

 //Print Student Results

 System.out.print("Fullname: "+lastname+", "+firstname);

 System.out.print('\n');

 System.out.print("Total Scores: "+total);

 System.out.print('\n');

 System.out.print("Average Scores: "+average);

 System.out.print('\n');

 System.out.print("Grade: "+grade);

}

}
