How to add javadocs to eclipse

To add Javadoc to Eclipse:

• download as many Javadoc packages as you want (they should be in zip or jar archives).
• Open your Eclipse preferences, and navigate to Java -> Installed JREs. Click on the default JRE you use, and click the Edit button on the right.
• In the window that pops up, click Add External JARs in the right column, and navigate to where you have the archives saved (you may want to save them somewhere out-of-the-way because if you delete the archives, your Javadoc won't work anymore).
• Select the archives, and click Open. This should recognize the Javadoc archives and help you with code-completion and documentation (you may have to restart your IDE for this to take effect).

You can find Java SE development kit 7 Documentation here

**You didn't specify what operating system you were on, so each OS may vary slightly.*

Right Click the JAR file in Project Explorer -> Properties -> From the left pane choose Javadoc Location -> enter the URL of your jar documentation.

Generally you can Google for: javadoc lib-name and then pickup the URL of the first site suggested by Google - going up a level.

For example Google returned this:
http://docs.oracle.com/javame/config/cldc/ref-impl/midp2.0/jsr118/index.html
so by going up one level, I mean:
http://docs.oracle.com/javame/config/cldc/ref-impl/midp2.0/jsr118/
