HolonJ creates Java class files from Forth source text, ready for the Java Virtual Machine. 

HolonJ applies the Forth method of programming to Java. With HolonJ you can build Java applications and applets in Forth. See the example applets Clock and TicTacToe.

• Fine source granularity allows clear factoring.
• Hierarchical organisation of the source, like a book with chapters and sections.
• Intrinsic hypertext, immediate access to the definition of every program element.
• Umbilical interactive development into (a monitor in) the JVM.
