## :books: General info
* Code from Java Programming Masterclass Section 15-285 JavaFx background tasks in Java - see [:clap: Inspiration](#clap-inspiration) below
* Progress bar shown below list with text detail of data added using simple for loop
* Employee Service now separated
* Progress bar and Progress label binding to

## :signal_strength: Technologies
* [Java v11](https://www.java.com/en/)
* [JavaFX v11](https://www.jetbrains.com/help/idea/javafx.html#create-project) - now a Java Plugin
* [class Collections](https://docs.oracle.com/en/java/javase/11/docs/api/java.base/java/util/Collections.html) static methods that operate on or return collections.
* [interface ObservableList](https://docs.oracle.com/javase/10/docs/api/javafx/collections/ObservableList.html) - a list that allows you to track changes
* [JavaFX FXML](http://tutorials.jenkov.com/javafx/fxml.html) an XML format that enables you to compose JavaFX GUIs like web GUIs in HTML
## :floppy_disk: Setup
* Open folder in an IDE such as IntelliJ. Run from `Main.java`
## :computer: Code Examples
* `Main.java` code to create a list observable then bind values to a FXML ListView
```java
public class Controller {
private Task> task;
@FXML
private ListView listView;
@FXML
private ProgressBar progressBar;
@FXML
private Label progressLabel;
public void initialize() {
task = new Task>() {
@Override
protected ObservableList call() throws Exception {
String[] names = {"Tim Buchalka",
"Bill Rogers",
"Jack Jill",
"Joan Andrews",
"Mary Johnson",
"Bob McDonald"};
ObservableList employees = FXCollections.observableArrayList();
for(int i=0; i<6; i++) {
employees.add(names[i]);
updateMessage(names[i] + " added to the list");
updateProgress(i + 1, 6);
Thread.sleep(200);
updateMessage("list complete");
}
return employees;
}
};
progressBar.progressProperty().bind(task.progressProperty());
progressLabel.textProperty().bind(task.messageProperty());
listView.itemsProperty().bind(task.valueProperty());
}
@FXML
public void buttonPressed() {
new Thread(task).start();
}
}
```
## :cool: Features
* Progress label shows each name as it is added to the list then a 'list complete' message is displayed
## :clipboard: Status & To-Do List
* Status: Working
* To-Do: Nothing
