Removes the item at anIndex This method works only if the JComboBox uses a mutable data model.

Usage

From source file:Main.java

public static void main(String[] argv) throws Exception {
    String[] items = { "item1", "item2" };
    JComboBox cb = new JComboBox(items);

    cb.removeItemAt(cb.getItemCount() - 1);
}
