$(20$ pts$)$ Implement a Banking System with Multiple Account Types

Create a parent class BankAccount with the following private attributes:

$$ accountNumber $($String$)$

$$ balance $($double$)$

Implement the following:

$$ A constructor to initialize accountNumber and balance.

$$ Getter methods for accountNumber and balance.

$$ A deposit$($double amount$)$ method that allows adding money to the account. Ensure

that the deposit amount is positive.

$$ A withdraw$($double amount$)$ method that allows withdrawing money from the account.

Ensure that the withdrawal amount is positive and does not exceed the balance.

Create two subclasses:

$1.$ SavingsAccount:

o Adds an attribute interestRate $($double$).$

o Implements a method applyInterest$()$ that adds interest to the balance based

on the interestRate.

$2.$ CheckingAccount:

o Adds an attribute overdraftLimit $($double$).$

o Override the withdraw$()$ method to allow withdrawing more than the balance, up

to the overdraft limit$.$

In the main method, create objects of SavingsAccount and CheckingAccount and demonstrate

deposit, withdrawal, and other operation
