today we got given this problem:
The LandL bank can handle at least 30 customers who have savings accounts.
* Design and then implement a program which manages deposits and withdrawls.
* Produce suitable error messages for invalid transactions
* Add a method which adds 3% to all accounts when it is invoked.
In class today we designed a class diagram in a group and this is our result: (tutor said tis fine and now we need to code it):
I am using netbeans to code this in java
I have a few questions please that would help me get started.
How many Main classes and normal classes do i need?
What should the programs actually do?
do i create 30 names for customers in an Array?
do i ask for user input by typing in a name and then ask what they want to do i.e. make a deposit, make a withdrawal and request balance
What do they mean by: Add a method which adds 3% to all accounts when it is invoked.
Many thanks for your help
