java - JavaFx 窗口很少

Question

如果几个 javaFx 窗口位于单独的类中，如何运行它们？

例如，在本例中:

public class Main {
    public static void main(String[] args) {
        Form1 form1 = new Form1();
        Form2 form2 = new Form2();

        // run form1
        // run form2
    }

    public static class Form1 extends Application {
        @Override
        public void start(Stage primaryStage) throws Exception {
            Stage stage = new Stage();
            stage.setScene(new Scene(new Group(new Button("Window 1"))));
            stage.show();
        }
    }

    public static class Form2 extends Application {
        @Override
        public void start(Stage primaryStage) throws Exception {
            Stage stage = new Stage();
            stage.setScene(new Scene(new Group(new Button("Window 2"))));
            stage.show();
        }
    }
}

我只需要同时显示两个窗口，但找不到任何简单的示例。

在javaFx中窗口被认为是阶段，因此不能创建多个窗口，可以考虑使用以下代码作为示例

public class Main extends Application {

@Override
public void start(Stage primaryStage) throws Exception{
    form1().show();
    form2().show();
}


public static void main(String[] args) {
    launch(args);
}

private Stage form1(){
    Stage stage=new Stage();
    stage.setTitle("Window 1");
    stage.setScene(new Scene(new Group(new Button("Window 1"))));
    return stage;
}
private Stage form2(){
       Stage stage=new Stage();
       stage.setTitle("Window 2");
       stage.setScene(new Scene(new Group(new Button("Window 2"))));
       return stage;
   }



}
