用户输入车辆名称和Id并单击Add Vehicle后，您将创建一个vehicle对象并将其存储在一个车辆数组列表中。
如何将GUI的输入数据存储到arraylist中？
import javafx.application.Application;
import javafx.event.ActionEvent;
import javafx.event.EventHandler;
import javafx.scene.Scene;
import javafx.scene.control.Button;
import javafx.scene.control.Label;
import javafx.scene.control.TextField;
import javafx.scene.layout.GridPane;
import javafx.stage.Stage;
public class Main extends Application {
public static void main(String[] args) {
Application.launch(args);
}
@Override
public void start(Stage primaryStage) throws Exception {
GridPane gridPane = new GridPane();
Label VehicleName = new Label("Vehicle Name ");
TextField VehicleNameF = new TextField();
Label Vehicle_ID = new Label("Vehicle ID");
TextField VehicleID = new TextField();
Button AddButton = new Button("Add Vehicle");
gridPane.setHgap(15);
gridPane.setVgap(15);
gridPane.add(VehicleName, 0, 0);
gridPane.add(Vehicle_ID, 0, 1);
gridPane.add(VehicleNameF, 1, 0);
gridPane.add(VehicleID, 1, 1);
gridPane.add(AddButton, 1, 2, 2, 1);
Scene scene = new Scene(gridPane, 300, 150);
primaryStage.setScene(scene);
primaryStage.show();
}

首先，为您的对象创建一个数组: Vehicules。
为了从GUI获取数据，您需要事件侦听器：
AddButton.setOnAction(e ->
{
Vehicule vehicule = new Vehicule();
vehicle.setVehicleId(VehicleID.getText());
vehicle.setVehicleName(VehicleNameF.getText());
Vehicules.add(vehicule);
//Vehicules is the array where you put all your objects.
})这回答了你的问题吗？

首先，您必须创建：
class Vehicle {
long vehicleId;
String vehicleName;
Vehicle(){
}
void setVehicleId(long vehicleID){
this.vehicleId=vehicleID;
}
long getVehicleId(){
return vehicleId;
}
void setVehicleName(vehicleName){
this.vehicleName=vehicleName;
}
String getVehicleName(){
return vehicleName;
}
}接下来，您必须创建新对象：
Vehicle vehicle1=new Vehicle();在您要添加指定值的位置
vehicle1.setVehicleName(Vehicle name-variable got from swing);
vehicle1.setVehicleId(Vehicle id-variable got from swing);列表如下：
List<Vehicle> vehiclesList=new ArrayList<Vehicle>()
vehiclesList.add(vehicle1);Stack Overflow用户

你遗漏了一些东西，比如：
AddButton.setOnAction(e ->
{
vehicle1.setVehicleId(VehicleID.getText());
vehicle1.setVehicleName(VehicleNameF.getText());
