How can I create mobile applications or games using NetBeans? I'm a newbie.
Try learning Java. It's the language used by Andriod OS and multiple webpages.
In order to create mobile applications or games using NetBeans IDE software, I recommend you check the tutorials provided by the developers on Documentation, Training & Support page. Also, you can use the guides that you can find using Google search engine or contact directly the support team and ask for help.
