Multiple instances of object based on one FXML

Question

I'm still pretty new to this so I did quite a reseach but couldn't found any suitable solution on SO or on the interet. How can I create multiple instances of object (you can call it a factory) based on one .fxml file. This particular .fxml file represents one record of movie information. And the result looks similar to this (I won't post here the fxml code, because it's not relevant):

So this is one record. As you can see I need sort of template. Let's say I got to display information about 5 movies, so I wish I could do :

    MovieView movieView = new MovieView(name, imageUrl, year, List<String> directors, 
    List<String> actors, Integer boxOffice, reviews);
    movieView.setImage(new Image(...));  // image change
    vbox.getChildren().add(movieView); // append to main panel 

five times and fill the VBox with five instances of the same class MovieView. How can this be done?

Answer 1

new keyword creates a new instance of an object in java.

Each call to new MovieView(....) will create a new instance of it. So if you need 5 instances, you would create it 5 times.

For example, you can do something like this to create 5 movie views and add them to a list

 List<MovieView> movieViews = new ArrayList<>();
 for (int i = 0; i < 5; i++) {
     // Creates a new instance on each iteration
     MovieView movieView = new MovieView(...);
     movieViews.add(movieView)
 }

Depending on your use case you'll have to pass in appropriate arguments and potentially create new instances of Image for each movie. Also, 5 could be any number here depending on how many instances you need. You can pass it as an argument to your method. This example should give you a starting point on how to implement your solution.
