Add a new class Checking Account that inherits from the BankAccount class, and has a double instance variable overdraftLimit in addition to the variables inherited from the superclass. Create a constructor for the Checking Account class that takes in the account number, account holder name, initial balance, account type and overdraft limit as input, and uses the super keyword to call the constructor of the superclass, passing in the account number, account holder name and initial balance, account type. Re-write the withdraw() method in the CheckingAccount class so that it first checks if the withdrawal amount is less than the current balance plus the overdraft limit. If it is, the withdrawal is allowed and the balance is updated. If not, the method should return an error message "Insufficient funds". Create a new method displayOverdraft Limit() that returns the overdraft limit of the Checking Account. In the BankAccountTest class, create a new object of type Checking Account with…
