如何将场景构建器连接到主类？

Question

我正在尝试将场景构建器连接到我的主类，但此错误消息显示在编译器

中

 Error: Could not find or load main class application.Main 

你会如何以正确的方式做到这一点？ 我做错了什么？

我对java非常新，所以有什么帮助！

import java.net.URL;
import java.util.ResourceBundle;
import javafx.event.ActionEvent;
import javafx.fxml.FXML;
import javafx.scene.control.Button;

public class Main {

    @FXML
    private ResourceBundle resources;

    @FXML
    private URL location;

    @FXML
    private Button bout0;

    @FXML
    private Button boutadd;

    @FXML
    private Button boutclear;

    @FXML
    private Button boutdec;

    @FXML
    private Button boutdivi;

    @FXML
    private Button boutegale;

    @FXML
    private Button boutmpty;

    @FXML
    private Button boutpoum;

    @FXML
    private Button boutpourc;

    @FXML
    private Button boutsous;


    @FXML
    void handleButtonAction(ActionEvent event) {
    }

    @FXML
    void initialize() {
        assert bout0 != null : "fx:id=\"bout0\" was not injected: check your FXML file 'Jdmd.fxml'.";
        assert boutadd != null : "fx:id=\"boutadd\" was not injected: check your FXML file 'Jdmd.fxml'.";

        assert boutdivi != null : "fx:id=\"boutdivi\" was not injected: check your FXML file 'Jdmd.fxml'.";
        assert boutegale != null : "fx:id=\"boutegale\" was not injected: check your FXML file 'Jdmd.fxml'.";
        assert boutmpty != null : "fx:id=\"boutmpty\" was not injected: check your FXML file 'Jdmd.fxml'.";
        assert boutpoum != null : "fx:id=\"boutpoum\" was not injected: check your FXML file 'Jdmd.fxml'.";
        assert boutpourc != null : "fx:id=\"boutpourc\" was not injected: check your FXML file 'Jdmd.fxml'.";
        assert boutsous != null : "fx:id=\"boutsous\" was not injected: check your FXML file 'Jdmd.fxml'.";
    }
 }
