import java.util.List;
import java.util.ArrayList;
import javafx.collections.*;

public class CollectionsDemo {
  public static void main(String[] args) {
    // Use Java Collections to create the List.
    List<String> list = new ArrayList<String>();

    // Now add observability by wrapping it with ObservableList.
    ObservableList<String> observableList = FXCollections.observableList(list);
    observableList.addListener(new ListChangeListener() {
      @Override public void onChanged(ListChangeListener.Change change) {
        System.out.println("Detected a change! ");
      }
    });

    // Changes to the observableList WILL be reported.
    // This line will print out "Detected a change!"
    observableList.add("item one");

    // Changes to the underlying list will NOT be reported
    // Nothing will be printed as a result of the next line.
    list.add("item two");

    System.out.println("Size: "+observableList.size());
