用戶輸入車輛名稱和 ID 并單擊添加車輛后，您將創(chuàng)建一個車輛對象并將其存儲到車輛的數(shù)組列表中。如何將來自GUI的輸入數(shù)據(jù)存儲到數(shù)組列表中？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，為您的對象創(chuàng)建一個數(shù)組：車輛。
要從 GUI 獲取數(shù)據(jù)，您需要事件偵聽器：
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.
})
這是否回答了您的問題？

首先，您必須創(chuàng)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;
}
}
接下來，您必須創(chuàng)建新對象：
Vehicle vehicle1=new Vehicle();
在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);
以及列表：
List<Vehicle> vehiclesList=new ArrayList<Vehicle>()
vehiclesList.add(vehicle1);

您缺少類似以下內容的內容：
AddButton.setOnAction(e ->
{
vehicle1.setVehicleId(VehicleID.getText());
vehicle1.setVehicleName(VehicleNameF.getText());
});
