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.

}
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();
}
}
