How to add element to existing JList

Question

Part of my code

 ArrayList<Item> i = g.getItems(); 
 Vector itemsVector = new Vector(i); 
 JList items = new JList(iemsVector); 

Later in the code I create new object which I want to add to JList. How can I do that?

Answer 1

private javax.swing.JList<String> list1;
list1.setFont(new java.awt.Font("Tahoma", 0, 24));

DefaultListModel listModel1 = new DefaultListModel();

String st="Working hard";
listModel1.addElement(r);

list1.setModel(listModel1);
