Create a console application that will function as a mock bank using solely Java 1.8. Persist your data in a text file. You may also write functionality to serialize your bank after every transaction. As a user, I can: * create an account with a unique email or username * log in * log out * deposit money * withdraw money * view balance To note: There are no strict requirements regarding the flow of operation for your program. Is your menu clear? Is user input validated? Do I have to log back in after each transaction? All important things to consider.
