Answer:

import java.util.Scanner;

public class KboatDiscount

{

public static void main(String args[]) {

Scanner in = new Scanner(System.in);

System.out.print("Enter Cloth length: ");

int l = in.nextInt();

System.out.print("Enter Total Amount of purchase: ");

double a = in.nextDouble();

System.out.println("Enter D for Dealer: ");

System.out.println("Enter R for Retailer: ");

System.out.print("Enter customer type: ");

char type = in.next().charAt(0);

type = Character.toUpperCase(type);

int d = 0;

switch (type) {

case 'D':

if (l <= 1000)

d = 20;

else if (l <= 2000)

d = 25;

          else

              d = 35;

          break;

           

          case 'R':

          if (l <= 1000)

              d = 15;

          else if (l <= 2000)

              d = 20;

          else

              d = 25;

          break;

           

          default:

          System.out.println("Wrong choice");

      }

     

      double disc = a * d / 100.0;

      double amt = a - disc;

       

      System.out.println("Amount to be paid = " + amt);

  }

}
