Preface

If you are new to programming and want to learn how to program, or if you have programming experience but are new to object-oriented programming (OOP) and want to learn OOP, I can't think of a better way to take that first step than through the use of Greenfoot .

Greenfoot provides a set of interactive visual tools coupled with the Java programming language that makes learning to program both interesting andproductive.

(Note that descriptions of the Greenfoot website contained herein are current as of 02/19/13.)

Overview

A visual interactive programming environment

The greenfoot overview page describes Greenfoot as an Interactive Visual World that "...teaches object orientation with Java."

When programming with Greenfoot, you "Create 'actors' which live in 'worlds' to build games, simulations, and other graphicalprograms."

Greenfoot is both instructive and enjoyable because it is visual and interactive. Visualization and interaction tools are built into the programmingenvironment.

Unlike Scratch and Alice (two programming environments for beginners that use a drag-and-drop approach to programming) , Greenfoot actors "are programmed in standard textual Java code, providing a combination of programming experience in a traditional text-basedlanguage with visual execution."

According to Wikipedia ,

"Greenfoot is an interactive Java development environment designed primarily for educational purposes at the high school and undergraduate level. It allows easy developmentof two-dimensional graphical applications, such as simulations and interactive games.

Greenfoot is being developed and maintained at the University of Kent and La Trobe University , with support from Oracle . It is free software, released under the GPL license. Greenfoot is available for Microsoft Windows , Mac OS X , Linux , Sun Solaris , and any recent JVM ."

Continuing with Wikipedia ,

"Greenfoot aims to motivate learners quickly by providing easy access to animated graphics, sound and interaction. The environment is highly interactiveand encourages exploration and experimentation. Pedagogically, the design is based on constructivist and apprenticeship approaches.

Secondly, the environment is designed to illustrate and emphasize important abstractions and concepts of object-oriented programming. Conceptssuch as the class/object relationship, methods, parameters, and object interaction are conveyed through visualizations and guided interactions. Thegoal is to build and support a mental model that correctly represents modern object-oriented programming systems."

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.

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
Prasenjit
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
Azam
name doesn't matter , whatever it will be change... I'm taking about effect on circumstances of the microscopic world
Prasenjit
how hard could it be to apply nanotechnology against viral infections such HIV or Ebola?
Damian
silver nanoparticles could handle the job?
Damian
not now but maybe in future only AgNP maybe any other nanomaterials
Azam
Hello
Uday
I'm interested in Nanotube
Uday
this technology will not going on for the long time , so I'm thinking about femtotechnology 10^-15
Prasenjit
can nanotechnology change the direction of the face of the world
Prasenjit Reply
At high concentrations (>0.01 M), the relation between absorptivity coefficient and absorbance is no longer linear. This is due to the electrostatic interactions between the quantum dots in close proximity. If the concentration of the solution is high, another effect that is seen is the scattering of light from the large number of quantum dots. This assumption only works at low concentrations of the analyte. Presence of stray light.
