                                    Total cost                                   Discount (in Percentage)

                                    Less than Rs. 2000                                  5%

                                    Rs. 2001 to Rs. 5000                              25%

                                    Rs. 5001 to Rs. 10000                            35%

                                    Above Rs. 10000                                   50%     

     Write a program to input the total cost and to compute and display the amount to be paid by the customer after availing the discount. Three methods also their input(), calculate() and display().

Solution

import java.io.*;

/**

 * class Showroom

 *

*/

public class Showroom

{

    private double cost;    // For cost

    private double dis;     // For Discount

    private double amt;     // For Amount

    void input()throws IOException

    {

        InputStreamReader in=new InputStreamReader(System.in);

        BufferedReader br=new BufferedReader(in);

        System.out.println("Enter Cost of the product:");

        cost=Double.parseDouble(br.readLine());

    }

    void calculate()

    {

        if(cost<=2000)

          dis = cost * 0.05;

        else if(cost>2000 && cost<=5000)

          dis = cost * 0.25;

        else if(cost>5000 && cost<=10000)

          dis = cost *0.35;

        else

          dis = cost * 0.5;

        amt= cost - dis;

    }    

    void display()

    {

        System.out.println("Cost of the product="+cost);

        System.out.println("Discount given="+dis);

        System.out.println("Amount Paid="+amt);

    }

    public static void main(String args[])throws IOException

    {

        Showroom ob=new Showroom();

        ob.input();

        ob.calculate();

        ob.display();

    }

}

Output:

 Enter Cost of the product:

5630

Cost of the product=5630.0

Discount given=1970.4999999999998

Amount Paid=3659.5
