Java(programming Language

Java is a programming language originally developed by James Gosling at Sun Microsystems(which is now a subsidiary of Oracle Corporation) and released in 1995 as a core component of Sun Microsystems' Java platform. The language derives much of its syntax from C and C++ but has a simpler object model and fewer low-level facilities. Java applications are typically compiledto bytecode (class file) that can run on any Java Virtual Machine (JVM) regardless of computer architecture. Java is a general-purpose, concurrent, class-based, object-oriented language that is specifically designed to have as few implementation dependencies as possible. It is intended to let application developers "write once, run anywhere". Java is currently one of the most popular programming languages in use, and is widely used from application software to web applications.[9][10]
The original and reference implementation Java compilers, virtual machines, and class librarieswere developed by Sun from 1995. As of May 2007, in compliance with the specifications of theJava Community Process, Sun relicensed most of its Java technologies under the GNU General Public License. Others have also developed alternative implementations of these Sun technologies, such as the GNU Compiler for Java, GNU Classpath, and Dalvik.

Five Element Of Multimedia

Multimedia is comprised of several elements including text, graphics, sound, video, and animation.The K-6 Multimedia kit includes tools and resources for working with each of these elements.Following are brief explanations of each multimedia element and how they can be used:TextText is perhaps the most fundamental element of any multimedia project. Students can useapplications such as AppleWorks and HyperStudio compose and edit their own text. Text-basedinformation can also be gathered from resource CDs and the Internet. Applications such asPhotoshop LE can be used to add visual effects to text to create a more appealing presentation.GraphicsGraphics can be incorporated into a multimedia project in the form of photographs or designs.Graphic images can be imported from a variety of resources such as the Internet, a digital camera,a scanner, or resource CDs such as Art Mania 12,000. Original graphic designs can be created withapplications such as HyperStudio, MovieWorks, and Photoshop LE.SoundSound can be added to a multimedia presentation from a variety of sources. Original sounds can berecorded using a microphone and programs such as HyperStudio, MovieWorks, or SmartSound.These applications, as well as QuickTime Pro, can also be used to import sounds from an audio CDor the Internet. Sound resource files that can be used in multimedia projects are also included onthe HyperStudio, MovieWorks, and SmartSound CDs.VideoMoving images or video can be incorporated into a multimedia project as QuickTime movies.QuickTime Pro, HyperStudio, and MovieWorks can be used with a camcorder or VCR to createand edit QuickTime movies. These programs can also import movies from the Internet and fromresource CDs such as The Archives of History. Movies that can depict a 360-degree panorama or amovable object can also be incorporated into a multimedia project. These virtual reality movies,often referred to as QuickTime VR movies, can be created with QuickTime VR Authoring Studiofor playback and be incorporated into programs such as HyperStudio, MovieWorks, andQuickTime Pro.AnimationGraphics that contain movement are often referred to as animation. Animation files can bedownloaded from the Internet in the form of animated GIF files and viewed with QuickTime Pro,HyperStudio, and MovieWorks. HyperStudio and MovieWorks can also be used to create and editboth frame and path animation.

- In the computer industry, these abbreviations are widely used to represent major steps or "generations" in the evolution of programming languages.1GL or first-generation language was (and still is) machine language or the level of instructions and data that the processor is actually given to work on (which in conventional computers is a string of 0s and 1s).2GL or second-generation language is assembler (sometimes called "assembly") language. A typical 2GL instruction looks like this: ADD 12,8An assembler converts the assembler language statements into machine language.3GL or third-generation language is a "high-level" programming language, such as PL/I, C, or Java. Java language statements look like this: public boolean handleEvent (Event evt) {switch (evt.id) {case Event.ACTION_EVENT: {if ("Try me" .equald(evt.arg)) {A compiler converts the statements of a specific high-level programming language into machine language. (In the case of Java, the output is called bytecode, which is converted into appropriate machine language by a Java virtual machine that runs as part of an operating system platform.) A 3GL language requires a considerable amount of programming knowledge.4GL or fourth-generation language is designed to be closer to natural language than a 3GL language. Languages for accessing databases are often described as 4GLs. A 4GL language statement might look like this: EXTRACT ALL CUSTOMERS WHERE "PREVIOUS PURCHASES" TOTAL MORE THAN $10005GL or fifth-generation language is programming that uses a visual or graphical development interface to create source language that is usually compiled with a 3GL or 4GL language compiler. Microsoft, Borland, IBM, and other companies make 5GL visual programming products for developing applications in Java, for example. Visual programming allows you to easily envision object-oriented programming class hierarchies and drag icons to assemble program components.

Difination Of Progaming Language

A programming language is an artificial language designed to express computations that can be performed by a machine, particularly a computer. Programming languages can be used to create programs that control the behavior of a machine, to express algorithms precisely, or as a mode of human communication.The earliest programming languages predate the invention of the computer, and were used to direct the behavior of machines such as Jacquard looms and player pianos. Thousands of different programming languages have been created, mainly in the computer field, with many more being created every year. Most programming languages describe computation in an imperative style, i.e., as a sequence of commands, although some languages, such as those that support functional programming or logic programming, use alternative forms of description.A programming language is usually split into the two components of syntax (form) and semantics (meaning) and many programming languages have some kind of written specification of their syntax and/or semantics. Some languages are defined by a specification document, for example, the C programming language is specified by an ISO Standard, while other languages, such as Perl, have a dominant implementation that is used as a reference.
