JavaFX obtaining data from table - javafx

Question

I have trouble obtaining data from table.
Get items doesn't work, and I'm stuck because there is lack of documentation. I get that Person is table model, but how can I use getFirstName from that maybe that is an answer. I have get but can not use that. Or should I stick to Swing for time being?
Here is a code:

Answer 1

You get items from the table by row, in this case that would be a person object. Then you use the get methods of the Person class to access fields. I'm guessing you want to use them in SaveFile(String, File) You should change it to something like saveFile(ObservableList<Person> persons, File file). Then you write the file something like
for (Person p : persons){
fileWriter.write(p.getFirstName()+","+
p.getLastName()/*etc..*/+"\n");
}

Answer 2

I did something like this. Got a hint on oracle forum :)
for (Person person : table.getItems()) {
String firstName = person.getFirstName();
String lastName = person.getLastName();
String email = person.getEmail();
String broj = person.getFixni();
String mob = person.getMobilni();
When i have them i will save them easily :)
