Java 3D:- Creating a 3d ball using java

By

Quoted from Wikipedia 
Java 3D is a scene graph based 3D application programming interface (API) for the Java platform. It ran atop either OpenGL orDirect3D until the version 1.6.0 which runs at the top of JOGL. Since version 1.2, Java 3D has been developed under the Java Community Process. A Java 3D scene graph is a directed acyclic graph (DAG).

Compared to other solutions, Java 3D is not only a wrapper around these graphics APIs, but an interface that encapsulates the graphics programming using a true object-oriented approach. Here a scene is constructed using a scene graph that is a representation of the objects that have to be shown. This scene graph is structured as a tree containing several elements that are necessary to display the objects. Additionally, Java 3D offers extensive spatialized sound support.

Java 3D and its documentation are available for download separately. They are not part of the Java Development Kit (JDK).

Before you could start creating java 3d programs you need to download and plugin it with your IDE.
you could download it from here.

Create a simple virus using java

By
What's my idea Before we start talking how we will create a simple flooder virus using java we must be clear about what is  the idea and how to implement it. So the idea is to create a program which will create  thousands of blank files in a drive you will don't believe but it could create file with  a speed of   1060+ files per second . How to implement it Now the problem is how we would do this?? So here is the answer .  First of all we will design a loop which will run  N  number of times where  N  is the number of files which we want to create. Then we will create a new File with the help of  createNewFile()  function of  java.io.File  class. The name of each file is the value of the variable which is used in the loop. Here is the sample virus program. /**  * **********This virus program is just for educational purpose   * author will not be re...

Capturing Screen Shot using java

By
Here i will tell you how to write a program using java which is capable of capturing screenshots(either whole or partial).And save it as an image. Which java API ? The java.awt.Robot class provides a useful method for capturing a screenshot.Here is the method prototype. BufferedImage createScreenCapture(Rectangle screenRect) It is clear from the prototype that this function returns a BufferedImage and takes a Rectangle class object (portion of the screen to capture) as the argument.The BufferedImage which is returned could be saved using ImageIO class write method.Lets begin with the program. 1) Capturing full screen In order to capture full screen using  createScreenCapture(Rectangle screenRect) screenRect should have the full screen size and in order to do that we will use Toolkit class of java. Rectangle screenRect =  new Rectangle( Toolkit.getDefaultToolkit().getScreenSize() ); Now here begins the whole program. /* ******...

Hijack Clipboard using java

By
What is Clipboard? The clipboard is a special location in your computer's memory that temporarily stores data that has been cut or copied from a document. This data can then be pasted to a new location. The clipboard will typically hold its information until you cut or copy something else, or log out of the computer. For example, a user may copy information from a word processor and paste that information into an e-mail message. What is Clipboard Hijack? A clipboard hijacking is an exploit in which the attacker gains control of the victim'sclipboard and replaces its contents with their own data, such as a link to a malicious Web site.For more details see  here . Hacking clipboard using java. Our java code will repeatedly change clipboard text with the hackers text, may be a irritating line ,or a URL to your site. We will use the Toolkit class to get the system clipboard and then we will use the Clipboard class to change the content of clipboard. ...
