Top-level online documentation

As of the date of this writing, you can view the top-level page of the documentation for Java Platform Standard Edition 7 at (External Link) .

A complicated page

When you first view that documentation page, it may appear to be very complicated. Of all the material on the page, the most important is probably the Application Programming Interface (API) , which is currently available via a link on the right side of the page labeled Java SE API .

However, you should not ignore the links to other information available on the top-level page . Those links will often contain information that you need, and that information canmake you more efficient in using the API documentation.


If you follow the Search link at the top of the page, you will arrive at a search engine page that gives you the ability to do a keyword search on the online documentation.

Downloading and installing Java

Of particular interest to most newcomers should be the links titled Installation Instructions and Java SE Downloads .

The Java Tutorials

Also very important is the link to The Java Tutorials . Once you reach those tutorials, of particular importance is the Path and CLASSPATH tutorial. (Many students trip on the path, the classpath, and the difference between the two.)

Java Platform, Standard Edition 7 API Specification

The API Specification is probably the most frequently used section of the entire documentation package.

Figure 1 shows a partial screen shot of what you should see when you first load the API Specification into your browser. (Note that this screen shot was cropped to force it to fit into this publication format.)

Screen layout

The purpose of providing this screen shot is to give you an idea of the general layout of the material as it appears on your screen. As you can see, thelayout consists of three frames when viewed in your HTML browser.

(A version without frames is also available by selecting the "No Frames" link at the top of the page. The version without frames is particularly usefulfor using the "page search" capability of your browser to find something on the page.)

The two leftmost frames

The upper-left frame contains a list of packages . The lower-left frame contains a list of the classes and interfaces that are contained in the package that is selected in the top-left frame.

(The default package selection in the upper-left frame is "All Classes".)

You make selections in these two frames (or in the link bar at the top of the page) to control the contents of the rightmost frame.

The rightmost frame

When you first access the API documentation (and when you select Overview at the top of the page), the rightmost frame contains summary information about all of the packages.

When you select a class in the lower-left frame (such as the JButton class for example) , the rightmost frame contains hyperlinked information about that class, including:

  • A visual class hierarchy diagram
  • Interfaces implemented by the class
  • Known subclasses of the class
  • Text description of the class
  • Summary of nested classes
  • Summary of fields defined in the class
  • Summary of fields inherited into the class
  • Summary and detailed information on constructors defined in the class
  • Summary and detailed information on methods defined in the class
  • List of methods inherited into the class

what is fullerene does it is used to make bukky balls
Devang Reply
are you nano engineer ?
fullerene is a bucky ball aka Carbon 60 molecule. It was name by the architect Fuller. He design the geodesic dome. it resembles a soccer ball.
what is the actual application of fullerenes nowadays?
That is a great question Damian. best way to answer that question is to Google it. there are hundreds of applications for buck minister fullerenes, from medical to aerospace. you can also find plenty of research papers that will give you great detail on the potential applications of fullerenes.
