How to style multiple ImageViews to not violate DRY in JavaFX11

Question

Is there a way to style multiple ImageViews and similar? For example, I have this code:

Image pic1 = new Image(getClass().getResourceAsStream("/pic1.png"));
ImageView picView1 = new ImageView(pic1);
picView1.setFitHeight(PIC_SIZE);
picView1.setPreserveRatio(true);
picView1.setSmooth(true);

Image pic2 = new Image(getClass().getResourceAsStream("/pic2.png"));
ImageView picView2 = new ImageView(pic2);

...

I would like to change the SIZE on all images, there are over 10 images. Could I create a Group and add all views to it and by that target all of the Objects to manipulate? Very new to JavaFX (11).

You could keep the reference to the ImageViews in a List.

List<ImageView> imageViews = new ArrayList<>();
...
Image pic1 = new Image(getClass().getResourceAsStream("/pic1.png"));
ImageView picView1 = new ImageView(pic1);
picView1.setFitHeight(PIC_SIZE);
picView1.setPreserveRatio(true);
picView1.setSmooth(true);
imageViews.add(picView1);

Image pic2 = new Image(getClass().getResourceAsStream("/pic2.png"));
ImageView picView2 = new ImageView(pic2);
imageViews.add(picView2);

...

When you need to change the size of the images you can just iterate through the list and set the fitHeight property to the value you want.

for (ImageView imageView : imageViews) {
    imageView.setFitHeight(PIC_SIZE);
}
