Button of Choice: Use ToggleButtons as RadioButtons

javafx-logo

For MQTT.fx I wanted to use ToggleButtons to e.g. choose the de coding of a MQTT Message or the QoS Level: I found out that in context of a ToggleGroup ToggleButtons behave different than RadioButtons in terms of selection/deselection: unlike RadioButtons ToggleButtons can still be set to unselected state. A RadioButton extends ToggleButton and overrides fire() (which is invoked when a user gesture indicates that an ...

The Parameterless Generic Method Antipattern

java-logo

A very interesting question was posted to Stack Overflow and reddit just recently about Java generics. Consider the following method: <X extends CharSequence> X getCharSequence() { return (X) "hello"; } While the unsafe cast seems a bit wonky, and you might guess there’s something wrong here, you can still go ahead and compile the following assignment in Java 8: Integer ...

Ceylon on mobile devices

ceylon-logo

Ceylon already runs on the JVM, whether bare-bones, via JBoss Modules, Vert.x, Java EE Servlet containers such as WildFly, or OSGi containers, as well as on JavaScript VMs such as Node.js and the browser.

java-logo

 Think application performance and reliability is the same? Think again. Are performance and reliability related? Or are these things mutually exclusive? I think the latter. Today, the reality is that IT sees application performance and reliability as the same thing, but that couldn’t be further away from the truth.

Code Review and Single Responsibility Principle

software-development-2-logo

According to the Single Responsibility Principle each unit in our code should have only one reason to change. Code Review, on the other hand, is a technique that helps us improve the quality of our code and increase its readability. I believe that you know both the principle and the technique. The question is: why do I juxtapose them in one article?
