JavaFX 8 Hello World for Eclipse

Learning JavaFX 8 on Eclipse is simple, once you get past the first Hello World style example. This JavaFX tutorial introduces SceneBuilder, FXML, and JavaFX 8 for Eclipse with an event (an ActionListener) and a controller class.

Believe it or not, I have a JavaFX 8 book that never once explains how to hook up events between a POJO and FXML generated from SceneBuilder—hundreds of pages of how-to material on JavaFX, and not one word on events. Pretty sad.

No such letdown here.

This tutorial demonstrates and explains creating a window that displays a button and a textfield in JavaFX 8, and then hooking them up in Eclipse, using SceneBuilder, so that clicking the button results in the words “Hello World” displaying in the textfield.

JavaFX … Information Alerts: Hello World

For decades, the traditional first program created when learning a computer programming language has been the “Hello World!” program. I like the tradition, so we’ll do the same here.

All Hello World does, is print out “Hello World!” As it turns out, there are lots of ways to do this in Java. They vary as widely as printing to a web page, or using a Swing dialog to pop up the words.

The two most cutting edge ways to do new Java apps are with GWT and JavaFX. GWT is too difficult for first time programmers, so I’ll stick to using the friendlier JavaFX for this tutorial.

This is part of the Java Tutorial series I’m writing for my son.

What is Java Used For?

Java is a computer programming language used to create software for servers, computers, tablets, phones, and all kinds of devices. Java creates programs found on web sites, in credit cards, in Blu-ray players, ATMs, HVACs, Minecraft and other games, robots, cars and programs found just about anywhere computers exist. Java applications run in small embedded microchips, normal computers, and massive multi-tier enterprise web-based applications.

Java is one of the most popular programming languages on the planet. Billions of devices run Java. Any sort of software can be written using Java.

Java programming is taught by most universities and colleges. This ensures a large base of developers for employers to choose from. Java is a mature language, developed in the 1990’s. Java software is in NASA’s Mars Rovers, so Java is an interplanetary language, too.
