add JList to JFrame

Question

I use these lines of code to add a JList to my frame but it doesn't do the job.

DefaultListModel model = new DefaultListModel();
model.addElement("one");
model.addElement("two");
JList list = new JList(model);
this.add(list);

Answer 1

you try this code

DefaultListModel<String> model = new DefaultListModel<>();
model.addElement("one");
model.addElement("two");
JList<String> list = new JList<>(model);
this.add(list);
