java - JavaFX fxml loader does not work properly -

testfx.java :

public class testfx extends application {     @override     public void start(stage primarystage) throws exception {         try{             fxmlloader loader = new fxmlloader();             loader.setlocation(getclass().getresource("/testfx/view/test.fxml"));             system.out.println("after set location");             //problem             anchorpane root = (anchorpane)loader.load();             system.out.println("does not happen");             testfxcontroller listcontroller = loader.getcontroller();             listcontroller.start();             scene scene = new scene(root, 200, 300);             scene.getstylesheets().add(getclass().getresource("application.css").toexternalform());             primarystage.setscene(scene);             primarystage.show();         }         catch (exception ex){             system.out.println("error");         }     }      public static void main(string[] args) {         launch(args);     } }  

testfxcontroller.java :

package testfx.view;  import javafx.collections.fxcollections; import javafx.collections.observablelist; import javafx.fxml.fxml; import javafx.scene.control.listview;  public class testfxcontroller {     @fxml listview<string> listview;     private observablelist<string> obslist;      public void start() {         // create observablelist         // arraylist         obslist = fxcollections.observablearraylist("giants", "patriots", "jaguars");         listview.setitems(obslist);     } } 

test.fxml :

<?xml version="1.0" encoding="utf-8"?> <?import javafx.scene.layout.anchorpane?> <?import javafx.scene.control.listview?> <anchorpane xmlns="http://javafx.com/javafx/8.0.40" xmlns:fx="http://javafx.com/fxml/1"     fx:controller="view.testfxcontroller">     <listview fx:id="listview"          anchorpane.topanchor="10"         anchorpane.leftanchor="10"          anchorpane.rightanchor="10"         anchorpane.bottomanchor="10" /> </anchorpane> 

when run testfx.java, system prints:

after set location   error 

this professor's code , cannot seem running. realized main problem in line of code anchorpane root = (anchorpane)loader.load(); have no idea how fix this, can help?

the value fx:controller attribute wrong (unless have different controller class 1 posted)

the controller want use: testfx.view.testfxcontroller

attribute value in fxml: view.testfxcontroller != testfx.view.testfxcontroller

assuming there no other error cannot reproduced information in question, fixing attribute value should work.
