Explanation / Answer

import java.util.Scanner;

public class CaseGrade

{

public static void main(String[] args)

{

Scanner input = new Scanner (System.in);

String name ;

int grade;

String exellent = "Exellent :";

String Exam 1 ="Exam 1 :";

String Exam 2 ="Exam 2 :";

String Exam 3 ="Exam 3 :";

int max = 100,90,100;

int min = 78,88,92;

int avg = 93.3,88.7;

int counter =0;

boolean repeat ;

while (repeat =true)

{

System.out.println("Enter Name : ");

name = input.next();

System.out.println("Enter Grade : ");

grade = input.nextInt();

if (grade == -1 )

{

avg = sum / counter;

System.out.println(" result = :");

System.out.println(exellent +" "+ veryGgood +" "+ good +" "+ pass +" "+fail);

System.out.println("maximum = "+ max +" ");

System.out.println("minimum = "+ min +" ");

System.out.println(" Average = " +avg);

System.exit(0);

}

switch (grade/10)

{

case 100:

case 9 :

Exam 1 += " "+ name + " " +grade+" ";

break;

case 8 :

Exam 2+= " " + name + " " +grade +" ";

break ;

case 7 :

Exam 3+= " " + name + " " +grade +" ";

break;

pass += " " + name + " " +grade +" ";

break;

default:

fail +=" " + name + " " +grade +" ";

break;

}

sum = sum + grade;

counter = counter + 1;

if (grade > max)

{

max = grade;

}

if (grade < min)

{

min = grade;

}

}

}

}
