import java.net.URL;
import javafx.application.Application;
import javafx.fxml.FXMLLoader;
import javafx.scene.Parent;
import javafx.scene.Scene;
import javafx.stage.Stage;
public class Main extends Application {
#Override
public void start(Stage primaryStage) throws Exception{
Parent root = FXMLLoader.load(getClass().getResource("as1.fxml"));
primaryStage.setTitle("Abdul-Rahim University");
primaryStage.setScene(new Scene(root, 800, 500));
primaryStage.show();
}
public static void main(String[] args) {
