Java spell checking with Jazzy (test #2)

By Alvin Alexander. Last updated: June 4, 2016

Java spell checking FAQ: Can you share a Java spell checking example?

Earlier I shared the source code for a simple Jazzy Java spell checking example. Next up, here's the Java source code from my second working Java spell checking program using the Jazzy spell checking tool. In this Java program I'm starting to get where I want, which is the ability to pass a String into Jazzy, and determine whether there are any misspellings in that String. Hopefully this is a little bit cleaner looking than my first Java spell checking example.

/**
 * In this test I think I'm starting to get a little smarter as far as how Jazzy works.
 * Here are some of the things I've done:
 * (1) I've switched from the FileWordTokenizer to the StringWordTokenizer.
 * (2) I learned that "spellChecker.addSpellCheckListener(this)" can only be run once.
 * (3) I've also started to abstract/extract some of the functionality out of the constructor and into other methods,
 * such as the new "populateListOfMisspelledWords" and "printWordsInMisspelledList" methods.
