Question

Write a Java program to calculate the fee for photo-coping document. The program will read an integer number from the keyboard which is the number of photocopies to be produced. The program will also calculate the fee as follow:

- if the number of copies is less than 100, each copy costs $0.10

- if the number of copies is between 100 and 499 (inclusive), each copy costs $0.05

- if the number of copies is between 500 and 999 (inclusive), each copy costs $0.03

- if the number of copies is 1000 and above, each copy costs $0.01

Finally, the program will print the fee.

Code (Text Format):

import java.util.*;
public class Calculate {
   public static void main(String[] args){
       /*Creating a Scanner object to get input from console*/
   Scanner sc = new Scanner(System.in);
       System.out.print("Enter the number of photocopies: ");
       /*Taking number of photocopies as input*/
   int num = sc.nextInt();
   double cost;
   /*Defining if else statements according to the conditions
   given in question*/
   if(num<100)
   cost = num * 0.10;
   else if(num>=100 && num<=499)
   cost = num * 0.05;
   else if(num>=500 && num<=999)
   cost = num * 0.03;
   else
   cost = num * 0.01;
   System.out.println("Cost = $"+cost);
   /*Its a good practice to close Scanner to avoid leaks*/
   sc.close();
   }

}

Sample Outputs:

Enter the number of photocopies: 20 Cost-$2.0

Enter the number of photocopies: 300 Cost$15.0 141

Enter the number of photocopies: 600 Cost $18.0

Enter the number of photocopies: 1150 Cost-$11.5
