How to Customize auto complete text field suggestion in JavaFx

Question

I am using ControlFx Textfields binding which works find. The thing is that the Suggestion popup values that Contains the inputed value. Like if i type in "M" values will be "Emma", "max", "rosemary", "Mathew". So my main Question is how to make the Suggestion to only bring out values Starting with "M" like "max",""Mathew" This is my code. It select name from database and add them to an ArrayList

PreparedStatement ps=db.DataBase.getCon().prepareStatement("select name from STUDENTINFO");
ResultSet res=ps.executeQuery();

        List list=new ArrayList();
        while(res.next()){
            list.add(res.getString("name"));
        }
        TextFields.bindAutoCompletion(textfieldSearch,list);

Here is a sample app that demos your question.

This snippet searches the original list for a substring and returns every item in the list that starts with the substring. this snippet should work with your code.

Key code:

TextFields.bindAutoCompletion(textFieldSearch, t -> {
    return list.stream().filter(elem -> 
    {
        return elem.toLowerCase().startsWith(t.getUserText().toLowerCase());
    }).collect(Collectors.toList());
});

Full app:

import java.util.ArrayList;
import java.util.List;
import java.util.stream.Collectors;
import javafx.application.Application;
import javafx.scene.Scene;
import javafx.scene.control.TextField;
import javafx.scene.layout.StackPane;
import javafx.stage.Stage;
import org.controlsfx.control.textfield.TextFields;

public class JavaFXApplication193 extends Application
{

    @Override
    public void start(Stage primaryStage)
    {
        List<String> list = new ArrayList();
        list.add("Max");
        list.add("moon");
        list.add("am");
        list.add("two");

        TextField textFieldSearch = new TextField();
        TextFields.bindAutoCompletion(textFieldSearch, t -> {
            return list.stream().filter(elem
                    -> {
                return elem.toLowerCase().startsWith(t.getUserText().toLowerCase());
            }).collect(Collectors.toList());
        });

        StackPane root = new StackPane(textFieldSearch);
        Scene scene = new Scene(root, 300, 250);

        primaryStage.setTitle("Hello World!");
        primaryStage.setScene(scene);
        primaryStage.show();
    }

    /**
     * @param args the command line arguments
     */
    public static void main(String[] args)
    {
        launch(args);
    }

}
