Design a class name ShowRoom with the following description: Instance variables/data members: String name: to store the name of the customer. long mobno: to store customer’s mobile number. double cost: to store the cost of the item purchased. double dis: to store the discount amount. double amount: to store the amount to be paid after discount. Methods: ShowRoom(): default constructor to initialize the data members void input(): to input customer name, mobile number, cost void calculate(): to calculate discount on the cost of purchased items, based on the following criteria Cost Discount(In percentage) Less than or equal to ₹ 10000 5 % More than ₹ 10000 and less than or equal to ₹ 20000 10 % More than ₹ 20000 and less than or equal to ₹ 35000 15 % More than ₹ 35000 20% void display()- To display customer, mobile number, amount to be paid after discount. Write a main() method to create an object of the class and call the above methods.

import java.util.Scanner; class ShowRoom { String name; long mobno; double cost,dis,amount; ShowRoom() //default constructor { name=""; mobno=0L; cost=0.0d; dis=0.0d; amount=0.0d; } void input() { Scanner kb = new Scanner(System.in); System.out.print("Enter your name: "); name=kb.nextLine(); System.out.print("Enter your Mobile Number: "); mobno=kb.nextLong(); System.out.print("Enter cost of item purchased: "); cost=kb.nextDouble(); } void calculate() { if(cost<=10000) { dis = cost * 5/100; amount = cost - dis; } else if(cost>10000&&cost<=20000) { dis = cost * 10/100; amount = cost - dis; } else if(cost>20000&&cost<=35000) { dis = cost * 15/100; amount = cost - dis; } else if(cost>35000) { dis = cost * 20/100; amount = cost - dis; } } void display() { System.out.println("Name of the customer: "+name); System.out.println("Mobile number : "+mobno); System.out.println("Amount to be paid after discount: "+amount); } } class UseShowRoom { public static void main(String[]args) { ShowRoom s = new ShowRoom(); s.input(); s.calculate(); s.display(); } }
