At a certain store they sell blank CDs with the following discounts:
* 10% for 120 or more
* 5% for 50 or more
* 1% for 15 or more
* no discount for 14 or less
Write a program that asks for a number of discs bought and outputs the correct discount. Use either a switch statement or if..elseif.. ladder statements. Assuming that each blank disk costs N$3.50. The program should then calculate the total amount paid by the buyer for the discs bought.

Answer 1

Answer:

public static void main(String[] args)

   {

       int cdCount;

       double cdCountAfterDiscount;

       DecimalFormat df = new DecimalFormat("$##.##"); // Create a Decimal Formatter for price after discount

       System.out.println("Enter the amount of CD's bought");

       Scanner cdInput = new Scanner(System.in);  // Create a Scanner object

       cdCount = Integer.parseInt(cdInput.nextLine());  // Read user input

       System.out.println("CD Count is: " + cdCount);  // Output user input

       if(cdCount <= 14 )

       {

           System.out.println("There is no discount");

           System.out.println("The final price is " + cdCount*3.5);

       }

       if(cdCount >= 15 && cdCount<=50)

       {

           System.out.println("You have a 1% discount.");

           cdCountAfterDiscount = (cdCount *3.5)-(3.5*.01);

           System.out.println("The final price is " + df.format(cdCountAfterDiscount));

       }

       if(cdCount >= 51 && cdCount<120)

       {

           System.out.println("You have a 5% discount.");

           cdCountAfterDiscount = (cdCount *3.5)-(3.5*.05);

           System.out.println("The final price is " + df.format(cdCountAfterDiscount));

       }

       if(cdCount >= 120)

       {

           System.out.println("You have a 10% discount.");

           cdCountAfterDiscount = (cdCount *3.5)-(3.5*.1);

           System.out.println("The final price is " + df.format(cdCountAfterDiscount));

       }

   }
