基于MVC的基本Swing应用程序

Question

所以我遇到了以下问题：我想用我的App类中的控制器实例初始化Swing构造函数。这是我启动回购和控制器的地方。当我想传递给swing Gui类时，控制器参数我意识到它有自己的main方法。

请您查一下代码，告诉我这是否正确？因为我不确定，我找不到从TUI应用程序到GUI应用程序的基本示例。谢谢！

  

App.java

package app;

import repository.*;
import view.View_gui;
import controller.*;

public class App{
    RepoInterface ri;
    ControllerInterface c;
    View_gui gui;

    public App() {
        ri = new Repo();
        c = new Controller(ri);
        gui = new View_gui(c);
    }

    public static void main(String[] args) {
        App app = new App();
    }
}
