JFLAP Formal Language Testing Software

JFLAP is a software designed for exploration of formal language concepts, covering a wide array of topics including nondeterministic finite automata, nondeterministic pushdown automata, multi-tape Turing machines, various types of grammars, parsing, and L-systems.


It empowers users to experiment with construction proofs, seamlessly transitioning between different forms. For instance, users can convert a nondeterministic finite automaton (NFA) to a deterministic finite automaton (DFA), then to a minimal state DFA, and further to a regular expression or regular grammar.

How to Install JFLAP on Ubuntu

To install JFLAP on your Ubuntu Linux system, first install flatpak and flathub on your system and restart it after the installation. Follow below commands for the installation steps.

flatpak remote-add --if-not-exists flathub https://flathub.org/repo/flathub.flatpakrepo

After that in the terminal app run below JFLAP flatpak install command.

flatpak install flathub org.jflap.JFLAP

And open it using below command

flatpak run org.jflap.JFLAP

And uninstall it using below commands.
