Looking for Java spell checker library [closed]

Another good library is JLanguageTool http://www.languagetool.org/usage/ It has a pretty simple api and does both spelling and grammar checking/suggestions.

JLanguageTool langTool = new JLanguageTool(Language.AMERICAN_ENGLISH);
langTool.activateDefaultPatternRules();

List<RuleMatch> matches = langTool.check("Hitchhiker's Guide tot he Galaxy");
for (RuleMatch match : matches) {
    System.out.println("Potential error at line " +
        match.getEndLine() + ", column " +
        match.getColumn() + ": " + match.getMessage());
    System.out.println("Suggested correction: " +
        match.getSuggestedReplacements());
}

You can also use it to host your own spelling and grammar web service.

You should check out Jazzy its used in some high profile Java applications. Two problems with it:

1. It has not been updated since 2005.
2. There is only English dictionary on their SourceForge page.

There are some third party dictionaries floating around. I had one for French, last time I used jazzy.
