Java J-Date Choosers cannot be resolved : my datechoosers are coming up as if they don't exist and I'm very confused what im doing wrong :( I originally had textfields for dates then swapped them to jdatechoosers and this is coming up for both areas(ignore that it says arrival time and departure time instead of departure date, it just needs to be updated  - https://i.imgur.com/yy2HOCP.png

    private Flight getinputFlightData() {
    		if (textField_FlightId.getText().isEmpty())
    			return null;
    		int flightID = Integer.parseInt(textField_FlightId.getText());
    		String departureAirport = textField_departureAirport.getText();
    		String arrivalAirport = textField_arrivalAirport.getText();
    		Date departureTime = dc_departureDate.getDate();
    		Date arrivalTime = dc_arrivalDate.getDate();;
    		
    		short flightSeats = Byte.parseByte(textField_FlightSeats.getText());
    		float flightPrice = Float.parseFloat(textField_FlightPrice.getText());
    		boolean isDelayed = Boolean.parseBoolean(textField_isDelayed.getText());
    
    		Flight flight = new Flight(flightID, departureAirport, arrivalAirport, departureTime, arrivalTime, flightSeats,	flightPrice, isDelayed);
    		return flight;
    	}
