Question

Java please

9:55 Note @13 simple lists of numbers. If the user selects option 2, your program should prompt for a list of integer grades (0 100, inclusive). When the list is entered print out the following statistics: total grades, the breakdown of grades by letter both count and percentage), the highest and lowest grades in the list, and the class average Example #1 Please enter a list of grades (0-100): 55 65 75 85 95-1 Total number of grades 5 Number of A's 1 (20%) Number of B's-1 (20%) Number of C's (20%) Number of D's-1 (20%) Number of F's (20%) Highest grade 95 Lowest grade 55 Class average 75 Updated Just Now

If you have any doubts, please give me comment...

import java.util.Scanner;

public class GradeStats{

public static void main(String[] args) {

Scanner in = new Scanner(System.in);

int no_A=0, no_B =0, no_C =0, no_D = 0, no_F=0;

System.out.println("Please enter a list of grades(0-100) :");

int grade = in.nextInt();

int n =0, highest = 0, lowest = 100;

double avg = 0.0;

while(grade!=-1){

n++;

if(grade>=90)

no_A++;

else if(grade>80)

no_B++;

else if(grade>70)

no_C++;

else if(grade>60)

no_D++;

else

no_F++;

if(highest<grade)

highest = grade;

if(lowest>grade)

lowest = grade;

avg += grade;

grade = in.nextInt();

}

avg /= n;

System.out.println("Total number of grades = "+n);

System.out.println("Number of A's = "+no_A+" ("+((no_A/(double)n)*100)+"%)");

System.out.println("Number of B's = "+no_B+" ("+((no_B/(double)n)*100)+"%)");

System.out.println("Number of C's = "+no_C+" ("+((no_C/(double)n)*100)+"%)");

System.out.println("Number of D's = "+no_D+" ("+((no_D/(double)n)*100)+"%)");

System.out.println("Number of F's = "+no_F+" ("+((no_F/(double)n)*100)+"%)");

System.out.println("Highest grade = "+highest);

System.out.println("Lowest grade = "+lowest);

System.out.println("Class average = "+avg);

}
