Selinium documention is available at seleniumhq.org/downloads in the javadocs links. We can import this documentations into our eclipse. We copy this link of java docs which is this https://seleniumhq.github.io/selenium/docs/api/java/index.html and then right click our project -->properties --> java build path --> libraries --> jar file client-combined -->javadoc location file and we type our above address there and remove "/index.html" from the end so basically paste this link https://seleniumhq.github.io/selenium/docs/api/java/ Click validate and it will says link is valid etc etc. And now if we hover over any class or interface in our project ,like for example if we hover over Webdriver it will show its descprition. We can click on any link in description and entire view will open. In that new window we can click on frames on the top and it will show more details or more classes etc.
