BlueJ Java IDE

BlueJ is a Java IDE that has a built-in editor, compiler, virtual machine and debugger for writing Java programs. It also has a graphical class structure display, supports graphical and textual editing, allows interactive object creation, interactive testing and incremental application building.

9) JIPE Java IDE

Jipe is a free Java IDE written in Java. It allows you to write and test Java applications and applets. Among its features are syntax highlighting, a Methods speedbar and project management. Since it’s written in Java, it is presumably portable to all operating systems that has a Java Virtual Machine. The author appears to have tested it on both Windows and Linux.

10) JCreator Java IDE LE (Light Edition)

The light edition of this IDE for Java has support for project management, a syntax highlighting editor, wizards, class viewer, package viewer, tabbed documents, JDK profiles (which allows you to work with multiple Java Development Kits), a customizable user interface, etc. JCreator runs on Windows 95, 98, NT4, 2000 (and presumably Windows ME too).

11) NetBeans

NetBeans is a cross-platform open source IDE for Java that comes with a syntax highlighting code editor that supports code completion, annotations, macros, auto-indentation, etc. It includes visual design tools (wizards) for code generation. It integrates with numerous compilers, debuggers, Java Virtual Machines and other tools.

12) RealJ

RealJ is a free Java development environment for Windows 95, 98 and NT, that: allows you to edit, compile and run Java applets and applications; has a class and function browser, syntax highlighting, integrated JDK reference in WinHelp format; and has the ability to go straight to the offending bit of source code by double-clicking on the compiler error message. You can also highlight a Java keyword or classname in the source editor, and go straight into the JDK reference by pressing F1. (Note: RealJ was formerly called FreeJava.)

Eclipse, JBuilder, and Sun Java Studio (in that order) appear to be the most popular choices, at least among the free and low-cost options.

• Eclipse. Free, open-source IDE. The most popular of the Java IDEs, but harder to set up and configure than the commercial ones. See this installation tutorial for setup help. Eclipse is the base IDE, but there are many Java-related plugins for Eclipse, and several commercial IDEs built on top of Eclipse. Here is information on a few:
  • MyEclipse. Nicely packaged version of Eclipse with many of the best free J2EE plugins already installed. Free download; $29.95 for a 1-year subscription to upgrades. If you are new to Eclipse, start with this version.
  • IBM WebSphere Studio. Powerful and popular J2EE IDE from IBM, the original developer’s of Eclipse.
  • M7 NitroX. Expensive but very powerful J2EE IDE based on Eclipse.
  • List of sites on Eclipse. Lists of Eclipse plugins, online forums, tutorials, etc.
  • Sites and news re Eclipse plugins.
  • Eclipse tutorials.
• Borland JBuilder. Borland JBuilder is a Java IDE for Windows, Solaris, and Linux. They offer a few different JBuilder versions:
  • JBuilder Enterprise Edition (lots of J2EE support including UML and app server integration),
  • JBuilder Developer Edition (missing some of the enterprise edition features, but still suppports applets, applications, JSP, servlets, Struts, unit testing, and team development).
  • JBuilder Foundation Edition (free version offering most of the JBuilder capabilities).
  • JBuilder WebLogic Edition (enterprise edition customized for BEA WebLogic)

Look at their feature matrix to compare and contrast the different versions.

• Sun Java Studio Creator. Java IDE for Windows, Solaris, and MacOS. Has very extensive drag-and-drop support for JavaServer Faces (JSF). Aims at making it easy for relative beginners to make complex server-side apps, but will be less popular for those not using JSF or for experts that prefer to work directly with the code. Built on the free, open-source NetBeans IDE.
• IBM WebSphere Studio Site Developer for Java. Java IDE for Windows and Linux. Expensive but very powerful IDE for servlets, JSP, and other J2EE development. Not limited to use with the WebSphere app server.

 

General Comparision between Programming Languages

Programming languages are used for controlling the behavior of a machine (often a computer). Like human languages, programming languages have syntactic and semantic rules used to define meaning.

There are thousands of programming languages and new ones are created every year. Few languages ever become sufficiently popular that they are used by more than a few people.

What Is 3G?

3G (or 3-G) is short for third-generation technology. It is used in the context of mobile phone standards. The services associated with 3G provide the ability to transfer simultaneously both voice data (a telephone call) and non-voice data (such as downloadinginformation, exchanging email, and instant messaging). In marketing 3G services, video telephony has often been used as the killer application for 3G.3G networks are not upgrades of 2G networks and do not operate on the same frequency spectrum; rather, entirely new networks need to be built and new frequencies need to be assigned to mobile operators. Induced euphoria led to huge spectrum-licensing fees in many countries, especially in Europe, where spectrum auctions went into the billions of euros. These spectrum licensing fees which were collected years before actual 3G development, together with the enormous investments necessary to build the all-new 3G networks, financially strained a number of mobile operators, delaying 3G roll-out worldwide except in Japan and South Korea, where such spectrum licensing fees were non-existent as the priority in those countries was set on national IT infrastructure development.

The first country which introduced 3G on a large commercial scale was Japan. In 2005, about 40% of subscribers used 3G networks only, with 2G being on the way out in Japan. It was expected that during 2006 the transition from 2G to 3G would be largely completed in Japan, and upgrades to the next 3.5G stage with 3 Mbit/s data rates were underway.

The successful 3G introduction in Japan showed that video telephony was not the killer application for 3G networks after all. The real-life usage of video telephony on 3G networks was found to be a small fraction of all services. On the other hand, downloading of music found strong acceptance by customers. Music download services in Japan were pioneered by KDDI with the EZchakuuta and Chaku Uta Full services.

Technically, 3G networks are not IEEE 802.11 networks. IEEE 802.11 networks are short range, primarily internet access networks, while 3G networks are wide area cellular telephone networks which evolved to incorporate high-speed internet access and video telephony to these networks.

Features:The most significant features offered by third generation (3G) mobile technologies are the momentous capacity and broadband capabilities to support greater numbers of voice and data customers – especially in urban centres – plus higher data rates at lower incremental cost than 2G.

By using the radio spectrum in bands identified, which is provided by the ITU for Third Generation IMT-2000 mobile services, it subsequently licensed to operators. 3G uses 5 MHz channel carrier width to deliver significantly higher data rates and increased capacity compared with 2G networks.

The 5 MHz channel carrier provides optimum use of radio resources for operators who have been granted large, contiguous blocks of spectrum. On the other hand, it also helps to reduce the cost to 3G networks while being capable of providing extremely high-speed data transmission to users.

It also allows the transmission of 384kbps for mobile systems and 2Mbps for stationary systems. 3G users are expected to have greater capacity and improved spectrum efficiency, which will allow them to access global roaming between different 3G networkings.

Standard 3G:

International Telecommunications Unit (ITU): IMT-2000 consists of five radio interfaces

• W-CDMA
• CDMA2000
• CDMA2001
• TD-CDMA / TD-SCDMA
• UWC-136
• DECT+

What Is MAML?

MAML is part of a new approach to help in Windows Vista. This approach is both more integrated with the software and more focused on user tasks. MAML provides a structre in which you can write user assistance information, which can then be presented to the user in a variety of locations.

An example of help using this schema (http://schemas.microsoft.com/maml/dev/2004/10) can be found on the Microsoft Office Online Assistance. Additionally, if the user chooses to get the latest online content, that content is downloaded to the local machine as MAML and transformed at runtime into HTML for display, just as the local content is.

MAML Topic Types
The following types of topic are currently in use in the new MAML based Office Online pages:
Training: to learn more about using programs, focus on features or activity areas and allow to suggest best practices. Courses are self-paced, and include graphics, animation, audio, and practice sessions for hands-on experience. They have an inherent browse sequence
Article: up-to-date information in the form of how-to, and tips information.
Topics :conceptual information about functionality and theory behind features.
Discussion: online Community where you can interact with fellow users, get your questions answered, share ideas, and learn more about products and technologies that interest you.

What Is Assistace Platform?

Assistance Platform (AP) is part of a new approach to help in Windows Vista. This approach is both more integrated with the software and more focused on user tasks.

AP is the technology used to deliver Help for windows vista.

It takes the MAML content and presents it to the user in an appropriate location.

Rather than present user assistance information as one help file with a large Table Of Contents, it can now appear in the following locations:

-Directly in User Experience
- Embeded Help
- Super Tooltips
- Ribbon
- Help pannels
-In application Context
- Help window
-No Context
- Help Centre

What Is WYSIWYG?

WYSIWYG is an acronym for What You See Is What You Get, used in computing to describe a system in which content during editing appears very similar to the final product. It is commonly used for word processors, but has other applications, such as Web (HTML) authoring.

Meaning:

• The term describes a user interface that allows the user to view something very similar to the end result while the document or image is being created. For example, a user can view on screen how a document will look when it is printed to paper or displayed in a Web browser.
• It implies the ability to modify the layout of a document without having to type or remember names of layout commands.

Modern software does a fairly good job of optimising the screen display for a particular type of output. For example, a word processor is optimised for output to a typical printer. The software often emulates the resolution of the printer in order to get as close as possible to WYSIWYG. However, that is not the main attraction of WYSIWYG, which is the ability of the user to be able to visualise what he or she is doing.

In many situations, the subtle differences between what you see and what you get are unimportant. In fact, applications may offer multiple WYSIWYG modes with different levels of “realism,” including:

• A composition mode, in which the user sees something somewhat similar to the end result but with additional information useful while composing, such as section breaks and non-printing characters, and uses a layout that is more conducive to composing than to layout.
• A layout mode, in which the user sees something very similar to the end result but with some additional information useful in ensuring that elements are properly aligned and spaced, such as margin lines.
• A preview mode, in which the application attempts to present a representation that is as close to the final result as possible.

Applications may deliberately deviate or offer alternative composing layouts from a WYSIWYG because of overhead or the user’s preference to enter commands or code directly.

 Historical notes:

• Before the invention of WYSIWYG, all text and control characters appeared in the same typeface and style with little indication of layout (margins, spacing, etc.). Users were required to enter code tags to indicate that some text should be in boldface, italics, or a different typeface or size. These applications used an arbitrary markup language to define the tags. Because of its simplicity, this method remains popular for some basic text editing applications (such as Wikipedia).
• The phrase was originated by a newsletter published by Arlene and Jose Ramos, called WYSIWYG. It was created for the emerging Pre-Press industry going electronic in the late 1970s. After 3 years of publishing, the newsletter was sold to employees at the Stanford Research Institute in California. The first conference on the topic was organized by Jonathan Seybold and the first technology popularized at Xerox PARC during the late 1970s when the first WYSIWYG editor, Bravo, was created on the Alto. The Alto monitor (72 pixels per inch) was designed so that one full page of text could be seen and then printed on the first laser printers. When the text was laid out on the screen 72 PPI font metric files were used, but when printed 300 PPI files were used — thus one would occasionally find characters and words slightly off, a problem that continues to this day. (72 PPI came from the standard of 72 “points” per inch used in the commercial printing industry.)
• Seybold and the researchers at PARC were simply reappropriating a popular catch phrase of the time originated by “Geraldine”, Flip Wilson’s drag persona from Rowan & Martin’s Laugh-In in the late 60s and and then on The Flip Wilson Show, (1970–1974).
• The Apple Macintosh system was originally designed so that the screen resolution and the resolution of the dot-matrix printers sold by Apple were easily scaled: 72 PPI for the screen and 144 DPI for the printers. Thus, the on-screen output of programs such as MacWrite and MacPaint were easily translated to the printer output and allowed WYSIWYG editing. With the introduction of laser printers, resolutions deviated from even multiples of the screen resolution, making WYSIWYG harder to achieve.
• Charles Simonyi, the PARC researcher responsible for Bravo, joined Microsoft in 1981 to start development of application programs at Microsoft. Hence, Bravo can be seen as the direct ancestor of Microsoft Word.
