[336209]

Вот мои программы:
package application;

import javafx.application.Application;
import javafx.fxml.FXMLLoader;
import javafx.scene.Parent;
import javafx.scene.Scene;
import javafx.stage.Stage;

public class Calculator extends Application
{

@Override
public void start(Stage primaryStage) throws Exception
{

Parent root = FXMLLoader.load(getClass().getResou rce("calc.fxml"));
primaryStage.setTitle("Калькулятор" );
primaryStage.setScene(new Scene(root));
primaryStage.show();
}


public static void main(String[] args)
{
launch(args);
}
}
