MicroProfile Config from a JavaFX application

Most of you probably heard about Eclipse Microprofile, including Microprofile Config. A quick try from a desktop application that uses JavaFX shows that it works without any additional configuration: just add a implementation dependency to your classpath and you can use microprofile config. See below a simple example.


package org.fxapps.microprofile.config;
import org.eclipse.microprofile.config.Config;
import org.eclipse.microprofile.config.ConfigProvider;
import javafx.application.Application;
import javafx.beans.property.SimpleStringProperty;
import javafx.scene.Scene;
import javafx.scene.control.Label;
import javafx.scene.control.TableColumn;
import javafx.scene.control.TableView;
import javafx.scene.layout.VBox;
import javafx.stage.Stage;
import javafx.util.Pair;
public class App extends Application {
public static void main(String[] args) {
launch();
}
@Override
public void start(Stage stage) throws Exception {
final Config config = ConfigProvider.getConfig();
TableView<Pair<String, String>> tableView = new TableView<>();
Label lblProperty = new Label();
TableColumn<Pair<String, String>, String> cKey = new TableColumn<>("Name");
TableColumn<Pair<String, String>, String> cValue = new TableColumn<>("Value");
cKey.setCellValueFactory(param -> new SimpleStringProperty(param.getValue().getKey()));
cValue.setCellValueFactory(param -> new SimpleStringProperty(param.getValue().getValue()));
cValue.setPrefWidth(500);
tableView.getColumns().add(cKey);
tableView.getColumns().add(cValue);
config.getPropertyNames().forEach(p -> {
String value = config.getValue(p, String.class);
tableView.getItems().add(new Pair<>(p, value));
});
String myCustomProperty = config.getValue("my.custom.property",String.class);
lblProperty.setText("Value for my.custom.property: " + myCustomProperty);
stage.setTitle("Default Properties");
stage.setScene(new Scene(new VBox(10, tableView, lblProperty), 800, 400));
stage.show();
}
}

Conclusion


Microprofile config works with JavaFX and this is great news. Microprofile is evolving quickly and JavaFX being able to work with it will give Java developers the ability to easily integrate desktop applications with java microservices.

Dancing lights with Arduino - The idea

I have been having fun with Arduino these days! In this article I am going to show how did I use an electret mic with Arduino to create a Dancing Lights circuit. Dancing Lights   I used to be an eletronician before starting the IT college. I had my own electronics maintenance office to fix television, radios, etc. In my free time I used to create electronic projects to sell and I made a few "reais" selling a version of Dancing lights, but it was too limited: it simply animated lamps using a relay in the output of a 4017 CMOS IC. The circuit was a decimal counter  controlled by a 555. 4017 decimal counter. Source in the image When I met Arduino a few years ago, I was skeptical because I said: I can do this with IC, why should I use a microcontroller. I thought that Arduino was for kids. But now my pride is gone and I am having a lot of fun with Arduino :-) The implementation of Dancing Lights with Arduino uses an electret mic to capture the sound and light leds...

Simplest JavaFX ComboBox autocomplete

Based on this Brazilian community post , I've created a sample Combobox auto complete. What it basically does is: When user type with the combobox selected, it will work on a temporary string to store the typed text; Each key typed leads to the combobox to be showed and updated If backspace is type, we update the filter Each key typed shows the combo box items, when the combobox is hidden, the filter is cleaned and the tooltip is hidden:   The class code and a sample application is below. I also added the source to my personal github , sent me PR to improve it and there are a lot of things to improve, like space and accents support.

Genetic algorithms with Java

One of the most fascinating topics in computer science world is Artificial Intelligence . A subset of Artificial intelligence are the algorithms that were created inspired in the nature. In this group, we have Genetic Algorithms  (GA). Genetic Algorithms  To find out more about this topic I recommend the following MIT lecture and the Nature of Code book and videos created by Daniel Shiffman. Genetic Algorithms using Java After I remembered the basics about it, I wanted to practice, so I tried my own implementation, but I would have to write a lot of code to do what certainly others already did. So I started looking for Genetic Algorithm libraries and found Jenetics , which is a modern library that uses Java 8 concepts and APIs, and there's also JGAP . I decided to use Jenetics because the User Guide was so clear and it has no other dependency, but Java 8. The only thing I missed for Jenetics are more small examples like the ones I will show i...
