推荐答案

您需要一种体系结构.

您的应用程序不需要具有可见的JFrame-因此，您的应用程序也可以具有多个JFrame.

您的主类-应用程序的起点-需要触发没有 GUI的基本应用程序.

该基本应用程序定义了生命周期.当它关闭时，应用程序完成.
基本应用程序有一项主要任务:保存数据，以便不同的JFrames可以访问它:

You need an architecture.

You application does not need to have a visible JFrame - therefor your application can also have multiple JFrames.

Your Main-class - starting point for the application - needs to trigger a basic application without GUI.

That basic application defines the lifecycle. When it is closed down the application is finished.
The basic application has one major task: it''s holding the data, so that different JFrames can access it:

public class Main {

  private static Facade oFacade = new Facade();
	
  public static void main(String[] args) {
    startFacade();
    startGUI();
  }

  private static void startGUI() {
    new GUI(oFacade);
  }

  private static void startFacade() {
    oFacade.init();
  }
}

外观的概念是Java开发中的常见模式(有关外观模式的维基百科 [

The concept of a facade is a common pattern in Java development (Wikipedia on facade pattern[^]

public class Facade {

  public void init() {
    // holding data 
  }
}

public class GUI{
  public GUI(Facade oFacade) {
    // controls JFrames
  }

  // needs to trigger end of lifecycle as the Main-class will not figure it otherwise and life happily forever and on.
}

基本上，这也是应用程序框架为您完成的工作-更加丰富，更加复杂.

That is basically also what an application framework does for you - much richer, much more complex.
