“Did you mean” search
corrections will be shown when JExamples can’t find a java example to
match a query you enter. When it can’t find an example for your query
it checks its database for classes and methods with names similar to
what you entered and then asks if you meant to search for one of those.


Each of the suggestions is a link you can click to run that query. JExamples.com is a free website that helps Java developers find high quality examples of virtually any Java API. JExamples uses code analysis and a search engine to find examples in many well known Java open source products (e.g. Ant, Spring, Tomcat). The search results are ordered according to user rating, so the examples voted best sort first; also, clicking one of the 5 line previews shown in the search results will display the entire source file.
