【问题描述】:
我正在尝试创建一个中间有几个选项卡的基本窗口,第一个选项卡包含一个表格。
每次我运行主 java 类时,它都会给我错误,即使我摆脱了表格和选项卡。
这是我的主文件:
package application;
import javafx.application.Application;
import javafx.stage.Stage;
import javafx.scene.Scene;
import javafx.scene.layout.BorderPane;
import javafx.fxml.FXMLLoader;
public class Main extends Application {
@Override
public void start(Stage primaryStage) {
try {
BorderPane root = (BorderPane)FXMLLoader.load(getClass().getResource("Sample.fxml"));
Scene scene = new Scene(root,400,400);
scene.getStylesheets().add(getClass().getResource("application.css").toExternalForm());
primaryStage.setScene(scene);
primaryStage.show();
} catch(Exception e) {
e.printStackTrace();
}
}
public static void main(String[] args) {
launch(args);
}
}
这是我的 fxml 文件:

任何帮助。我找不到任何东西,但可能是我的 fxmlloader.load 文件源?我真的不知道。
