Question

Instructions

Write a Java program that asks the user t enter five test scores. The program should display a letter grade for each score and the average test score. Write the following methods in the program: * calcAverage -- This method should accept five test scores as arguments and return the average of the scores. * determineGrade -- This method should accept a test score as an argument and return a letter grade for the score, based on the following grading scale. Score Letter Grade 90-100 A 80-89 B 70-79 C 60-69 D Below 60 F

        double num1 = z.nextDouble();                                                           // scanning 5 scores
        double num2 = z.nextDouble();
        double num3 = z.nextDouble();
        double num4 = z.nextDouble();
        double num5 = z.nextDouble();
      
        double average = calcAverage(num1, num2, num3, num4, num5);                             // passing scores to average
       char grade = determineGrade(average);                                                   // passing average to grade
      
        System.out.println("The average of Scores is: " +average);                              // printing average
        System.out.print("The grade of Test Score is: " +grade);                                // printing grade
    }
}

I hope the above snippets, information, and the explanation will help you out!
