Prepare the library for use

Once you have downloaded the zip file, you will need to extract the folder named bookClasses from the zip file and store it somewhere on your computer's disk.

Library documentation

When you examine the contents of the bookClasses folder, you will see that in addition to source code and compiled class files for thelibrary, the folder also contains javadoc documentation for the library in afolder named doc and some other material as well. Go to the doc folder and open the file named index.html in your browser to view the documentation.

Put the library on the classpath

You will need to put the path to the bookClasses folder on your classpath in order to incorporate classes from the library into yourprograms.

Figure 4 . Putting the library on the classpath.
del *.class javac -cp .;M:\bookClasses *.javajava -cp .;M:\bookClasses Prob01

Figure 4 shows three commands that you can execute at a Windows command prompt to

  • Delete the class files from the current folder or current directory -- Google current directory if you don't recognize the term,
  • Compile the source-code files in the current folder , and
  • Execute the compiled version of a program named Prob01 in the current folder

The commands shown in Figure 4 assume that the bookClasses folder is in the root directory on the M-drive. The bookClasses folder will likely be in a different location on your computer. They also assume thatyou are compiling and running a program having its main method in a class named Prob01 in a file named Prob01.java .

Be sure to include the period and the semicolon shown before the M in Figure 4 . This tells the Java compiler and the Java Virtual Machine to search first in the current folder before searching elsewhere on the disk for the required files.

You can also put the three commands in a batch file and run the batch file to avoid having to type the three commands each time you need to compile and runthe program. In that case, you should add a pause command following the other three commands.

Note that this batch file must be placed in the same folder that contains the file named Prob01.java , and that folder must be your "current directory. DO NOT attempt to execute the commands shown in Figure 4 from inside the bookClasses folder."

If you are using an IDE such as DrJava, JCreator, or JGrasp, see the instructions for the IDE to learn how to set the classpath in the IDE.

Two versions of Hello World

It is often useful to have the code for a simple program to test your system. This section presents two versions of the classical Hello World program. The first version is a simple text version that doesn't use Ericson's library.This version can be used to confirm that the Java Development Kit (JDK) is properly installed on your computer.

The second version is a graphic version that does require Ericson's library.This version can be used to confirm proper installation and use of the library.

A text version of Hello World

The simple program shown in Listing 1 causes the words Text Hello World to be displayed on the standard output device when the program is compiled andexecuted.

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.

Mostly, they use nano carbon for electronics and for materials to be strengthened.
is Bucky paper clear?
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.

good afternoon madam
what is system testing
what is the application of nanotechnology?
In this morden time nanotechnology used in many field . 1-Electronics-manufacturad IC ,RAM,MRAM,solar panel etc 2-Helth and Medical-Nanomedicine,Drug Dilivery for cancer treatment etc 3- Atomobile -MEMS, Coating on car etc. and may other field for details you can check at Google
anybody can imagine what will be happen after 100 years from now in nano tech world
after 100 year this will be not nanotechnology maybe this technology name will be change . maybe aftet 100 year . we work on electron lable practically about its properties and behaviour by the different instruments
name doesn't matter , whatever it will be change... I'm taking about effect on circumstances of the microscopic world
how hard could it be to apply nanotechnology against viral infections such HIV or Ebola?
silver nanoparticles could handle the job?
not now but maybe in future only AgNP maybe any other nanomaterials
I'm interested in Nanotube
this technology will not going on for the long time , so I'm thinking about femtotechnology 10^-15
