Electronic Shop Discount Program - ICSE 2009 Computer Science

An electronics shop has announced the following seasonal discounts on the purchase of certain items:

Purchase amount in Rs. Discount on Laptop Discount on Desktop PC
0 – 25000 0.0% 5.0%
25001 – 57000 5.0% 7.6%
57001 – 100000 7.5% 10%
More than 100000 10.0% 15.0%

Write a program based on the above criteria to input name, address, amount of purchase and the type of purchase (L for Laptop and D for Desktop) by a customer. Compute and print the net amount to be paid by a customer along with his name and address.
(Hint: Discount = (discount rate / 100) * amount of purchase,
Net amount = amount of purchase – discount)

Java 

import java.util.Scanner;
class Shop{
    public static void main(String args[]){
        Scanner in = new Scanner(System.in);
        System.out.print("Name: ");
        String n = in.nextLine();
        System.out.print("Address: ");
        String a = in.nextLine();
        System.out.print("Amount of purchase: ");
        int amt = Integer.parseInt(in.nextLine());
        System.out.print("Type of purchase: ");
        char type = in.nextLine().charAt(0);
        double dp = 0.0;
        switch(type){
            case 'L':
            case 'l':
            if(amt <= 25000)
                dp = 0.0;
            else if(amt <= 57000)
                dp = 5.0;
            else if(amt <= 100000)
                dp = 7.5;
            else
                dp = 10.0;
            break;
            case 'D':
            case 'd':
            if(amt <= 25000)
                dp = 5.0;
            else if(amt <= 57000)
                dp = 7.6;
            else if(amt <= 100000)
                dp = 10.0;
            else
                dp = 15.0;
        }
        double da = dp / 100 * amt;
        double net = amt - da;
        System.out.println("Name: " + n);
        System.out.println("Address: " + a);
        System.out.println("Net amount: " + net);
    }
}

Output

 
 OUTPUT : 
Name: Ricky
Address: Kolkata
Amount of purchase: 65000
Type of purchase: L
Name: Ricky
