Student Range Program - Java Programs

A list contains marks in the subject Computer Applications for ‘N’ number of students. Write a program to create an array of size ‘N’ and store the marks. Check and print the number of students falling into the different ranges given below:

100 – 80
79 – 60
59 – 40
39 – 20
19 – 0

Java


import java.util.Scanner;
class Ranges{
    public static void main(String[] args){
        Scanner in = new Scanner(System.in);
        System.out.print("N = ");
        int n = Integer.parseInt(in.nextLine());
        int a[] = new int[n];
        int r[] = new int[5];
        System.out.println("Enter marks:");
        for(int i = 0; i < a.length; i++){
            a[i] = Integer.parseInt(in.nextLine());
            if(a[i] >= 80 && a[i] <= 100)
                r[0]++;
            else if(a[i] >= 60 && a[i] <= 79)
                r[1]++;
            else if(a[i] >= 40 && a[i] <= 59)
                r[2]++;
            else if(a[i] >= 20 && a[i] <= 39)
                r[3]++;
            else if(a[i] >= 0 && a[i] <= 19)
                r[4]++;
        }
        System.out.println("100 - 80: " + r[0]);
        System.out.println("79 - 60: " + r[1]);
        System.out.println("59 - 40: " + r[2]);
        System.out.println("39 - 20: " + r[3]);
        System.out.println("19 - 0: " + r[4]);
    }
}
