Specification

Design and implement a class called Building Society that manages user accounts using an appropriate graphical user interface in Swing. Each instance of the BuildingSociety class will have a name and a maximum number of accounts that it can handle.

The BuildingSociety class should have the following methods:

• openAccount ( allow a user to open a new Credit Union account)
• closeAccount (allow an account holder to close an account on condition that the balance is currently zero)
• makeLodgement ( allow an account holder to lodge money)
• makeWithdrawal (allow an account holder to withdraw money from their account)
• requestOverdraft (allow an account holder to request a new overdraft limit).

Each BuildingSociety Account should have a number, a name, a current balance and an overdraft limit. The methods for each account are:

• lodgement ( make a lodgement)
• withdrawal (remove a sum of money from the account on condition that there are sufficient funds available to meet the request)
• balance (check current balance)
• overdraftLimit ( check current overdraft limit)
• setNewOverdraft ( set the overdraft limit to some given value).
