A superclass Bank has been defined to store the details of a customer. Define a subclass Account that enables transactions for the customer with the bank. The details of both the classes are given below:Class name: Bank Data members/instance variables: name: stores the name of the customer accno: stores the account number P: stores the principal amount in decimals Member functions/methods: Bank(….): parameterized constructor to assign values to the instance variables void display (): displays the details of the customer Class name: Account Data member/instance variable: amt: stores the transaction amount in decimals Member functions/methods: Account(…): parameterized constructor to assign values to the instance variables of both the classes void deposit(): accepts the amount and updates the principal as p=p+amt void withdraw(): accepts the amount and updates the principal as p=p-amt If the withdrawal amount is more than the principal amount, then display the message “INSUFFICIENT BALANCE”. If the principal amount after withdrawal is less than 500, then a penalty is imposed by using the formula. p=p-(500-p)/10 void display(): displays the details of the customer Assume that the superclass Bank has been defined. Using the concept of Inheritance; specify the class Account giving details of the constructor(…), void deposit(), void withdraw() and void display() The superclass and the main function need not be written.

import java.util.Date 

public class Account 

{ 

private int id=0 

private double balance = 0 

private static double annualRate = 0 

private Date dateCreated = new date(); 

Account () 

{ 

id = 0; 

balance = 0.0; 

AnnuallnterestRate = 0.0; 

} public Account (int newId, double newBalance) { id = newld; balance = newBalance; 

} 

Account (int newId, double newBalance, 

double new AnnuallnterestRate) 

{ 

id = newId; 

Balance = newBalance; 

AnnualInterestRate = new AnnualInterestRate; 

} 

public int get Id() 

{ 

return id; 

} 

public double get Balance() 

{ 

return balance; 

} 

public double get AnnuallnterestRate() 

{ 

return AnnuallnterestRate; 

} 

double get Monthlylnterest Rate()

{ 

return AnnualInterestRate/12/100 + bal; 

} 

double withdraw (double amount) 

{ 

return balance - = amount; 

} 

public double withdraw (double amt, date current date, date preset) 

{ if (getBalance() < amount) 

{ 

System.out.println("Amount is larger than current balance"); 

if (current date.after (preset) 

{ System.out.printing("Amount exceed balance"); 

return super;

 withdraw (amount); }
