Bank...Exception

Create a class  BankAccount having the members as given below:

accNo  integer

custName string

accType string (indicates ‘Savings’ or ‘Current’)

balance double

Include the following methods in the BankAccount class:

void deposit(double amt);

void withdraw(double amt);

double getBalance();

           

deposit(double amt) method allows you to credit an amount into the current balance. If amount is negative, throw an exception NegativeAmount to block the operation from being performed.

withdraw(double amt) method allows you to debit an amount from the current balance. Please ensure a minimum balance of Rs. 1000/- in the account for savings account and Rs. 5000/- for current account, else throw an exception InsufficientFunds and block the withdrawal operation. Also throw an exception NegativeAmount to block the operation from being performed if the amt parameter passed to this function is negative.

getBalance() method returns the current balance. If the current balance is below the minimum required balance, then throw an exception LowBalanceException accordingly.

Have constructor to which you will pass, accno, cust_name, acctype and initial balance.

And check whether the balance is less than 1000 or not in case of savings account and less than 5000 in case of a current account. If so, then raise a LowBalanceException.

In either case if the balance is negative then raise the NegativeAmount exception accordingly.
