Define a class named CloudStorage with the following specifications:
Member Variables:
int acno – stores the user’s account number
int space – stores the amount of storage space in GB purchased by the user
double bill – stores the total price to be paid by the user
Member Methods:
void accept() – prompts the user to input their account number and storage space using Scanner class methods only.
void calculate() – calculates the bill total price based on the storage space purchased using the pricing table provided:

Storage range	Price per GB (Rs)
First 15 GB	15
Next 15 GB	13
Above 30 GB	11

void display() – displays the account number, storage space and bill to be paid.

Write a main method to create an object of the class and invoke the methods of the class with respect to the object.

import java.util.Scanner;
class CloudStorage{
    int acno;
    int space;
    double bill;
    public void accept(){
        Scanner in = new Scanner(System.in);
        System.out.print("Account number: ");
        acno = in.nextInt();
        System.out.print("Space: ");
        space = in.nextInt();
    }
    public void calculate(){
        if(space <= 15)
            bill = space * 15;
        else if(space <= 30)
            bill = 225 + (space - 15) * 13;
        else
            bill = 420 + (space - 30) * 11;
    }
    public void display(){
        System.out.println("Account No. " + acno);
        System.out.println("Storage space: " + space);
        System.out.println("Bill: " + bill);
    }
    public static void main(String[] args){
        CloudStorage obj = new CloudStorage();
        obj.accept();
        obj.calculate();
        obj.display();
    }
}
