這基本上是一個簡單的生產(chǎn)者-消費者應(yīng)用程序。代碼示例如下：public class MyMainClass extends Application {    // blocking queue that will be shared among my prcesses    BlockingQueue bq;    public static void main(String[] args) {        launch(args);    }    @Override    public void start(Stage primaryStage) {        primaryStage.setTitle("Hello World!");        // parameters I wont the Thread passes to the server socket        TextArea parameters = new TextArea("parameters-for-the-server");        // setting the Producer button        Button btnProducer = new Button();        btnProducer.setText("Start Producer");        btnProducer.setOnAction(new EventHandler<ActionEvent>() {            @Override            public void handle(ActionEvent event) {              /* ReadSocket connects to a web sockets,                 reads strings and saves them into a shared blocking queue: bq*/                ReadSocket rs = new ReadSocket(bq);                new Thread(rs).start();            }            // setting the Consumer button            Button btnConsumer = new Button();            btnConsumer.setText("Start Consumer");            btnConsumer.setOnAction(new EventHandler<ActionEvent>() {                @Override                public void handle(ActionEvent event) {                  /* ReadSocket connects to a web sockets,                     reads strings and saves them into a shared blocking queue: bq*/                    Consumer c = new Consumer(bq);                    new Thread(c).start();                }        });        StackPane root = new StackPane();        root.getChildren().add(btn);        primaryStage.setScene(new Scene(root, 300, 250));        primaryStage.show();    }}我的教授說，如果我希望它們可用于其他對象，我應(yīng)該在構(gòu)造函數(shù)中傳遞值。我ReadSocket應(yīng)該看起來像這樣：public class ReadSocket{  BlockingQueue bq;  ReadSocket(bq){    this.bq = bq;    // more code  }那么，這是否意味著我必須傳遞我的價值觀，例如：ReadSocket rs = new ReadSocket(bq, parameters.getText()); 即使ReadSocket不是直接使用它們而是基于parameters? 這樣做正確嗎？還有其他更好的方法嗎？
