Implementing statecharts in Java using design patterns

This online tutorial is part of a bachelor-level software modeling course taught by Tom Mens at the University of Mons (Belgium). You will learn how to create a Java program that implements a composite statechart specified in the Yakindu statechart tool. After introducing the Java class structure using UML class diagrams in the Visual Paradigm modeling tool, we show how to implement the statechart in Java with Eclipse, by making use of the State design pattern and the Singleton design pattern, and relying on a Swing user interface.
