Develop a new class called LoanAccount, based on BankAccount( from Lab 10). This class has an overdraft facility, so that the user can withdraw money up to the overdraft limit. The class must store an overdraft limit for the account. It must also store the current interest rate, but this is the same for all accounts (it is not part of any one account).
The constructor will require a name and account number to be specified, and will invoke the constructor of the BankAccount class and also set the overdraft limit to 0. Also, the withdraw method from BankAccount will have to be overridden in this class, so that a negative balance is permitted. You will need to add a protected setBalance method to BankAccount , that changes the balance without checking it, since BankAccount does not normally allow negative balances.
The public interface must also include the following additional methods:
1. set/get the interest rate
2. set/get the overdraft limit
3. calculate projected interest (0 if the balance is positive, otherwise multiply current balance by current interest rate)
