Question
Help with this data structure project.
Can you help make this program: an ATM system that required the user to input an account number and a pin to access an account and from there they could either deposit, withdraw, or check their balance. They are supposed to be saved so that you could run the program and access the account again to change the balance
Implement two types of accounts, checking and savings that have access limits. For example you could make savings accounts have a limit of 3 withdrawals per month.
Basically, ATM program with 2 identification checks (ID and pin), deposit, withdraw, check balance, and saving of accounts and their balance.
Tell me the sorting method you used (Selction, etc) and the type of data structure (Array, etc). And please includes comments and javadoc. Thank you. The sorting may be used for example to get cash from checking to saving (i.e Insertion Sort)
