    Default Error when trying to hide JComboBox Option.

    Cannot switch on a value of type Object. Only convertible int values, strings or enum variables are permitted


    I'm trying to hide and option using switch statement but this is the error i receive.
    could someone help me fix this please?

      public void actionPerformed(ActionEvent e)
            {
                if(e.getSource() == comboDest1)
                {
                    switch(comboDest1.getSelectedItem())
                    {
                        case "Crete":
                            //throw away the old accomodation array, and assign a new array to it with specific accomodations
                            Accomodation = new String[]{"Select your Accomodation","Hotel", "Villa", "Bed & Breakfast"};
                            //throw away the old combobox and make a new one with the new accomodation array
                            comboAccom1 = new JComboBox(Accomodation);
                            break;
     
                    }
                }
            }
            }

    What don't you understand about the error message?

    Actually, this error presents an opportunity for you to get into the JComboBox API to understand the error message. While you're there, review the available JComboBox methods and consider another, more elegant approach to rebuilding the array for the new JComboBox.
