Preface

This module is one of a series of modules designed to teach you about Object-Oriented Programming (OOP) using Java.

I cannot overemphasize the importance of Oracle's Java documentation to aspiring Java programmers. The documentation package, which can be downloadedfor installation and local access or accessed online, contains a wealth of information.

In my opinion, it is not possible to write Java programs of any substance without frequent reference to the documentation. No one canmemorize everything that they need to know to be a successful Java programmer.

(Note that each time Oracle releases a new version of the Java Development Kit (JDK), they also release a new version of the documentation. Therefore, asnew versions are released, the links provided in this document may become outdated and may not take you to the latest version of the documentation.However, you should be able to find the latest documentation via an online search.)

Viewing tip

I recommend that you open another copy of this module in a separate browser window and use the following links to easily find and view the figureswhile you are reading about them.

Discussion

Small core language, large class library

The Java Platform Standard Edition programming environment consists of a small core programming language and a large class library.

(As of the date of this writing, you can view The Java Language Specification online. This specification will tell you just about everything that most programmers need to know about the corelanguage.)

The size of the class library grows with the release of each new version of the JDK, because each new version provides capabilities that didn't exist in theprevious version. New capabilities are added through the addition of new classes and new interfaces to the library.

The true power of Java resides in the class libraries

Once you understand how OOP is implemented in Java and you get beyond while loops, if statements, and other fundamental programming concepts, virtually all the power of Javaresides in:

  • Classes, interfaces, and methods in the various class libraries that you use directly.
  • Classes, interfaces, and methods in the various class libraries that you extend.
  • New classes, interfaces, and methods that you and others define.

You will always use material from Oracle's standard class libraries. You will often use material from other libraries that you create yourself, or that youobtain from sources outside of Oracle (such as Barb Ericson's multimedia library , for example) .

what is fullerene does it is used to make bukky balls
Devang Reply
are you nano engineer ?
s.
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.
Tarell
what is the actual application of fullerenes nowadays?
Damian
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.
Tarell
what is the Synthesis, properties,and applications of carbon nano chemistry
Abhijith Reply
Mostly, they use nano carbon for electronics and for materials to be strengthened.
Virgil
is Bucky paper clear?
CYNTHIA
carbon nanotubes has various application in fuel cells membrane, current research on cancer drug,and in electronics MEMS and NEMS etc
NANO
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?
