Click on the "Class" search button and type the name of the class in. JDocs.com will show you a list of matching classes after you've typed at least 2 characters. For e.g., if you type Str you will see a list of classes that begin with the words Str (such as String, StringBuffer, etc.). Only the first 15 matches are shown. If there are more matches, the bottom of the list has a "more" link that will show the full list of matches. You can use wildcards (*) in your keyword to control the matches.

You can search for packages and methods by selecting the respective search button and typing the name of the package or method in. You can use wildcards to match packages and methods as well.

To browse through the contents of a library, click on the "API List" button and simply type the name of the library into the search box. Click on the link to navigate to the page for the library.

By default the search results are limited to the favorite libraries (by default JDK 1.5 implemented by Apache Harmony, Spring, Hibernate and Log4j). This is necessary so that a) you don't get results from libraries that you are not using and hence irrelevant and b) you don't get multiple results from different versions of the same library. Click on the Favorites button to select libraries you want included in your favorites or uncheck the button that restricts searches to your favorites. You can save your favorite libraries by registering an account with the site.

Set your favorite libraries (by clicking on the Favorites button) to the libraries you use and check the box that says "Limit search to favorites." You can also save the favorites by creating an account.

The class detail page gives you a wealth of information. The top header bar gives you links to the library and package the class belongs to. There are also shortcut links [LIST] to quickly view the list of classes in the same package or list of packages in the same library as the class.

The detail page then displays the signature of the class including annotation and generics. Below this are a set of tabs. The first tab displays the description for the class as provided in the Javadoc. The second tab shows you inheritance information (going all the way to java.lang.Object). It also shows you a list of direct derivatives and a link to see all derived classes (to any degree of derivation).

The Members tab shows all the members along with relevant javadocs. There is also a link to the line of source where the member appears. A member navigator window allows you to quickly jump to any member's description. The member navigator also has a "inherited members" panel that shows you all inherited methods with links to definitions of those methods in the parent classes. The Usage tab shows you the use of the class across all libraries in your profile. This includes information such as constructors that take the class as a parameter, methods that return the class, etc. The Source tab shows you the source code (where available). The source tab also has a navigator window to enable you to jump to member definitions with ease. The last tab, Notes allows you to leave publicly viewable notes about the class.

The Sun JDK documentation are copyrighted and Sun is not licensing it to external websites. However, begining with Sun JDK 1.7, an open source release is available under the Open JDK project. This version and all future versions that are also open-sourced will be available through JDocs.

Our next release will include functionality to allow end users to upload libraries. For now, send us an e-mail and we will be glad to add your library in.
