There are 2 *. FXML file, each of which is connected to your *. java file. In one.fxml Yes imageview FX: id = "image" How from twocontroller.java Place the image in imageview file one.fxml . It seems to me that the code below may well come out only you need to get imageview with one.fxml
stackpane sp = new stackpane ();
Image img = new image ("javafx.jpg");
Imageview imgview = new imageview (img);
sp.getchildren (). Add (imgView);
In general, I can not understand why I get nullpointerexception
Here is the code Two.java
one con;
Image img = new image (getClass (). GetResource ("logo.png"). ToexternalForm ());
ImageView image = new imageview (img);
con .Anchorpane.getchildren (). Add (image);
and if it is written in one.java That everything works without errors.
Inheritance is not suitable, error crashes:

There are assumptions that the wrong image add, although I tried to change the name, the same result.

Well, it may be not the best option from possible, but it works exactly because I need.
onecontroller.java
@ fxml
Public Static ImageView Image;
@Fxml
Public Anchorpane Anchorpane;
@Fxml
Public Void Initialize (URL URL, ResourceBundle Br) {
click ();
}
void click () {
TWOCONTROLLER CONTR = NEW TWOCONTROLLER ();
image = new image ();
If (image! = NULL) {
Image i = null;
Image IM = CONTR.Setimage (I);
image.setimage (CONTR.Setimage (IM));
Anchorpane.Getchildren (). Add (image);
}
}
twocontroller.java
....
Public Image Setimage (image img) {
Image img = null;
i = img;
i = new image (getClass (). GetResource ("logo.png")));
Return img;
}
