 java代码:

package xyz.hashdog.class112;

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

import java.io.File;

/**

public class Launch extends Application {

    public static void main(String[] args) {
        Application.launch(Launch.class,args);
    }

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

        FXMLLoader fx = new FXMLLoader();
        fx.setLocation(fx.getClassLoader().getResource("fxml/class112.fxml"));
        AnchorPane load  = fx.load();
//        AnchorPane load = (AnchorPane)fx.load(getClass().getClassLoader().getResourceAsStream("fxml/class112.fxml"));
        Scene s= new Scene(load);
        primaryStage.setScene(s);
        primaryStage.setTitle("hashdog");
        primaryStage.setWidth(500);
        primaryStage.setHeight(300);
        //设置窗口不可拉伸
        primaryStage.setResizable(false);
        primaryStage.show();






    }

}
