The remaining Java code

The remaining code that you will need to include in your Java program file is shown in Listing 23 .

Simply copy this code, without modifications, and paste it at the end of your file.

Listing 23 . The remaining Java code.
//ONLY THE CODE ABOVE THIS LINE CAN BE MODIFIED //##################################################////DO NOT MODIFY ANY OF THE FOLLOWING CODE. }//end main//----------------------------------------------------// //Create a String variable containing the namespace// URI to reduce the amount of typing that is required // later. Note that the variable name is short and// easy to type. static String ns = "http://www.w3.org/2000/svg";//For clarity, create strings containing the name of// the element that is constrained by the DTD (the // root element), the Public ID of the DTD, and the// System ID of the DTD. static String dtdConstrainedElement = "svg";static String dtdPublicID = "-//W3C//DTD SVG 1.1//EN"; static String dtdSystemID ="http://www.w3.org/Graphics/SVG/1.1/DTD/svg11.dtd";static DocType docType = new DocType(dtdConstrainedElement,dtdPublicID,dtdSystemID); }//end class

The SVG graphics library

The Java code for my SVG graphics library is provided in Listing 26 . All you need to do is copy this code into a file named SvgLib21.java and place that file in the same folder with your program code. I will explain later what you need to doafter that.

The graphics library in Listing 26 was updated on 08/11/11 to add new features. However, the text in this module has not been updated to illustrate the use ofthose new features. The downloadable documentation has been updated to include those features.

IVEO compatibility

Note that the library was revised on 08/07/11 to add a title element to each shape element and to the svg element. As a result, when the output SVG file is opened in the IVEO viewer and you click on a shape, information about that shape is spoken by IVEO. When you open the file in the IVEO viewer , the text content of the title element belonging to the svg element is spoken.

Note that you must be careful about the order in which you add theshapes to the drawing. For example, a rectangle that is added after a line is added can cover the lineand prevent the information about the line from being spoken by IVEO even though the rectangle may be transparent.Therefore, for IVEO compatibility, you must not allow one shape object to cover another shape object.

Graphics library documentation

Click here to download a zip file named SvgLib21Docs.zip containing standard Java documentation for the graphics library.

To view the documentation, YOU MUST EXTRACT the contents of the zip file into an empty folder. (Forgive me for shouting, but my students are constantly forgetting to extract material from a zip file before they try to use thatmaterial.) Then open the file named index.html in your browser. If you are unfamiliar with the format of the documentation, theexplanation at (External Link) might be helpful.

Another sample program

Another sample program that produces a different drawing is provided in Listing 27 . This program contains extensive usage instructions in the form of comments for all of the capabilities of my SVG graphics library. If youencounter any difficulties using the library, you should consult the instructions in that program.

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.

so some one know about replacing silicon atom with phosphorous in semiconductors device?
s. Reply
Yeah, it is a pain to say the least. You basically have to heat the substarte up to around 1000 degrees celcius then pass phosphene gas over top of it, which is explosive and toxic by the way, under very low pressure.
Do you know which machine is used to that process?
