The grades will all be integers. .Read in the grades and store them in an array of the correct size. Call the method below (which you will create) to calculate and return the highest value in the Array public static int findMax(int[] theArray) .Call the method below (which you will create) to print a line for each grade in the format displayed in the sample output on next page public static void printGrades (int[] theArray, int highestGrade)

Answer 1

Please find my implementation.

import java.util.Scanner;

public class Grade {

  

   public static int findMax(int[] theArray) {

      

       int max = theArray[0];

       for(int i=1; i<theArray.length; i++)

           if(theArray[i] > max)

               max = theArray[i];

       return max;

   }

  

   public static void printGrades(int[] theArray, int higestGrade) {

      

       for(int i=0; i<theArray.length; i++) {

          

           char ltr;

          

           if(theArray[i] >= Math.abs(higestGrade- 10))

               ltr = 'A';

           else if(theArray[i] >= Math.abs(higestGrade - 20))

               ltr = 'B';

           else if(theArray[i] >= Math.abs(higestGrade - 30))

               ltr = 'C';

           else if(theArray[i] >= Math.abs(higestGrade - 40))

               ltr = 'D';

           else

               ltr = 'F';

          

           System.out.println("Student "+i+" score is "+theArray[i]+" and grade is "+ltr);

       }

   }

  

   public static void main(String[] args) {

      

       Scanner sc = new Scanner(System.in);

      

       System.out.println("Enter the number of grades");

       int n = sc.nextInt();

      

       // creating an array

       int[] grades = new int[n];

      

      

       // reading grades

       System.out.println("Enter 4 grades separated by space");

      

       for(int i=0; i<n; i++)

           grades[i] = sc.nextInt();

      

       sc.close();

      

       int max = findMax(grades);

      

       //System.out.println(max);

      

       printGrades(grades, max);

   }

}

Sample run:

Enter the number of grades

4

Enter 4 grades separated by space

40 55 70 58

Student 0 score is 40 and grade is C

Student 1 score is 55 and grade is B

Student 2 score is 70 and grade is A

Student 3 score is 58 and grade is B
