Super simple java swing jlist question that I just can't figure out! <p>Ok, so I am working on a homework assignment, and I am using SWING to make a GUI for a Java project, and I am running into troubles with JList.</p> <p>I have a customer object that I have made and set attributes to, and I want to add the object into a TreeMap. I want to hook up the Treemap so that any and all objects that are in the map will populate (the name attribute anyway) inside of the JList.</p> <p>I have done a lot of looking around, and am seeing a lot about coding these things from scratch but little dealing with Swing implementation. I put my customer object into my map and then I would like for my JList to reflect the map's contents, but I don't know how to hook it up.</p> <pre><code> customers.put(c.getName(), c); this.customerList.(What can I do here? add Customer object?? I can't find what I need); </code></pre> <p>Thanks for your help!!!</p>
