Java program to calculate the fine assuming that a book is returned N days late

A library charges a fine for books returned late. Following are the fines:

First five days : 40 paise per day.

Six to Ten days : 65 paise per day.

Above ten days : 80 paise per day.

Design a program to calculate the fine assuming that a book is returned N days late.

import java.util.*;
class Fine
{
    public static void main(String arr[])
    {
        int N;
        float f;
        Scanner sc=new Scanner(System.in);
        System.out.println("Enter the no. of days the book is returned late:");
        N=sc.nextInt();
        if (N<=5)
            f=0.40f*N;
        else if (N<=10)
            f=0.40f*5+(N-5)*0.65f;
        else
            f=0.40f*5+0.65f*5+(N-10)*0.80f;
        System.out.println("Fine="+f);
    }
}
