JavaFX ComboBox - Display text but return ID on selection

Question

I have a Database table with airports, each airport has a name and an ID.

In JavaFX I have a form, with a ComboBox, the combobox needs to display all the ai

Answer 1

Your Airport Class.. .

public class Airport {

private int id;
private String name;

public Airport(int id, String name) {
    super();
    this.id = id;
    this.name = name;
}

public int getId() {
    return id;
}

public void setId(int id) {
    this.id = id;
}

public String getName() {
    return name;
}

public void setName(String name) {
    this.name = name;
}

}// class Airport

Create Observable list of Airport

ObservableList airports = FXCollections.observableArrayList();
airports.add(new Airport(1, "Beijing Capital International Airport"));
airports.add(new Airport(2, "Los Angeles International Airport"));
airports.add(new Airport(3, "London Heathrow Airport"));

Set item of your combo box. .

combo.setItems(airports);

After this when you run your program you get the output like this. ..

To get name of Airports you have to need to override toString method in Airport class.

@Override
public String toString() {
    return this.getName();
}

After this you will get output like.. .

Now to get the id of selected airport you can set an event handler. .

private void setEventOnAirport() {
    combo.setOnKeyReleased(event -> {
        if (event.getCode().equals(KeyCode.ENTER)) {
            Airport airport = combo.getSelectionModel().getSelectedItem();
            System.out.println(airport.getId());
        }
    });
}

By this function you can see the ID of selected Airport. . .
