This week's book giveaway is in the OCAJP 8 forum. We're giving away four copies of OCA Java SE 8 Programmer I Study Guide and have Edward Finegan & Robert Liguori on-line! See this thread for details.
I am not sure why we need to implement this method:
// Creates a new record in the database (possibly reusing a // deleted entry). Inserts the given data, and returns the record // number of the new record. public long createRecord(String  data) throws DuplicateKeyException;
The user interface section say that you need to implement the following: It must allow the user to book a selected record, updating the database file accordingly and search.
To use create method, I will need a screen where I ask user to enter all fields. Currently, I do not have this screen. Not sure I need it.
Can someone please tell me, where would I call this method?
