1、jtable的使用：

             DefaultTableModel model;        Vector data=new Vector();        for(Email email:emails)        {            Vector row=new Vector();            row.add(email.getSend());            row.add(email.getContent());            row.add(email.getDate());            data.add(row);        }                Vector columnNames=new Vector();        columnNames.add("发件人");        columnNames.add("邮件内容");        columnNames.add("收件时间");        model=new DefaultTableModel(data, columnNames);        //GmailTableModel model = new GmailTableModel();        jTable1.setModel(model);        model.fireTableDataChanged();

2、javaFX加载fxml界面并且向controller传入参数

 private void showMainUI(Stage newStage, String fxml) {        FXMLLoader loader = new FXMLLoader();        InputStream in = getClass().getResourceAsStream(fxml);        loader.setBuilderFactory(new JavaFXBuilderFactory());        loader.setLocation(getClass().getResource(fxml));        Pane page = null;        try {            page = (Pane) loader.load(in);            Scene scene = new Scene(page);            MainController controller = loader.getController();            controller.setStage(newStage);            newStage.setScene(scene);            newStage.sizeToScene();            newStage.show();        } catch (IOException e) {            e.printStackTrace();        } finally {            try {                in.close();            } catch (IOException ex) {                Logger.getLogger(MyGmail.class.getName()).log(Level.SEVERE, null, ex);            }        }    }

3、javafx创建新窗体:

 Stage stage = new Stage();                        //create root node of scene, i.e. group            Group rootGroup = new Group();                      //create scene with set width, height and color            Scene scene = new Scene(rootGroup, 200, 200, Color.WHITESMOKE);                       //set scene to stage            stage.setScene(scene);                      //set title to stage            stage.setTitle("New stage");                       //center stage on screen            stage.centerOnScreen();                       //show the stage            stage.show();
