Did you try by downloading project from GitHub (you have a link in the description)? Altough, I suspect only on one cause: You are not assigning any value to firstName variable. If you pass Person instance into insert method by previously creating Person instance like this: Person person = new Person("John", "Smith"); then your error is probably in body of constructor in Person class. Check whether this.firstName = firstName; exists.
