GUI ComboBox 3

// Create a read-only combobox; the combobox is read-only // in that it does not allow the user to type in a new item. // The combobox still allows programmatic changes to its items. String[] items = {"item1", "item2"}; JComboBox cb = new JComboBox(items); // Add an item to the start of the list cb.insertItemAt("item0", 0); // Add an item after the first item cb.insertItemAt("item0.5", 1); // Add an item to the end of the list cb.addItem("item3"); // Remove first item cb.removeItemAt(0); // Remove the last item cb.removeItemAt(cb.getItemCount()-1); // Remove all items cb.removeAllItems();
