This is a improved version of this old spell checker that I've built in Java based in the original Peter Norvig spell checker built on python.
This version is a way faster then the Java demonstration version.
After clone this repo, just enter it's folder and compile Spelling.java. Then run it in the command line with the incorrect word as param:
javac Spelling.java
java Spelling speling
This should output spelling.
