hey guys i was wondering if someone could help, i have to create an address book in java that can add, delete, search as well as import details from a file.
so far iv got the GUI down (ish) iv set it over 2 frames, one to edit the data and containing alll the buttons and the other at the moment is just a JList containing the details such as name, address, phone number.
However, i cant get the jlist to take more then the name on a single line and the other details just get printed in the JList below each other.
am i using the wrong thing? maybe a JTextField or JTable? and would either of those be easyer when importing?
any help would be great thanks

}in an ideal world id like the data to be displayed as followed:
Frank, 86 Highlight Street, 0168168111, 07745729486.
so name, address, home number, moble number.
this is one of my first java projects so any help atal would be great, im starting to think that maybe a big text field would be better then a list because i also need the app to be able to import data from a file.
