Fill combobox from a column in jtable
<p>This is a school assigment and I am not allowed to use SQL. I have a JTable with the following columns:</p>

<p><code>Cruise_name;Ship_name;Departure_location;Departure_date</code></p>

<p>I am saving these items in a <code>.txt</code> file called <code>cruising.txt</code> which looks like this: </p>

<pre><code>Atlantis;SOS FOR LOVE;Koper;1.1.2020;
Program;M.Hamilton;Neverland;1.1.2020;
Atlantis;Derpina;Lonely ;1.1.2020;
...
...
</code></pre>

<p>On a separate tab I need to populate a combobox with <code>Cruise_name</code> items I either get from that table directly (somehow) or make an ArrayList that reads the first item in every line from the <code>.txt</code> file. At this moment I don't know how to do either. I could really use some help, please!</p>
