For deposit method:
if(amount<0)
{ // do something to indicate invalid data
}
else
{ // proceed with deposit
}
Similar for withdrawal.
Modifications of this kind is much easier if the class and associated methods are available.
I suggest you try to code the best you can and post what you have, and where you have a difficulty.
Enhance bank account class by adding preconditions for the constructor and the deposit method that require the amount parameter to be atleast zero, and a precondition for the withdraw method that requires amount to be a value between 0 and the current balance.Use assertions to test the preconditions.
