The language derives much of its syntax from Cand C++ but has a simpler object model and

fewer low-level facilities Java is a general-purpose, concurrent, class-based, object-oriented language that isspecifically designed to have as fewimplementation dependencies as possibleIt is intended to let application developers "writeonce, run anywhere

Java is currently one of the most popularprogramming languages in use, and is widelyused from application software to webapplications

Java technology is based on the concept of asingle Java virtual machine (JVM) -- atranslator between the language and theunderlying software and hardwareB y using the Java complier, you can change thesource code into byte codeThe byte code can be run on any platformhaving Java interpreter that can convert thebyte code into codes suitable for the operating

system

James Gosling, Mike Sheridan, and PatrickNaughton initiated the Java language project in June

1991The language was initially called Oak after an oaktree that stood outside Gosling's office; it went bythe name Green later, and was later renamed Java,from a list of random wordsGosling aimed to implement a virtual machine and alanguage that had a familiar C/C++ style of notation Java Programming Language is simplified toeliminate language features that cause common

programming errorsSun Microsystems released the first publicimplementation as Java 1.0 in 1995. It promised"Write Once, Run Anywhere" (WORA), providingno-cost run-times on popular platforms

Java is simple : Java was designed to be easy to use and istherefore easy to write, compile, debug, and learn than otherprogramming languages. The reason that why Java is muchsimpler than C++ is because Java uses automatic memoryallocation and garbage collection where else C++ requires theprogrammer to allocate memory and to collect garbage

Java is object-oriented : Java is object-oriented becauseprogramming in Java is centered on creating objects,manipulating objects, and making objects work together. Thisallows you to create modular programs and reusable code

Java is platform-independent : One of the most significantadvantages of Java is its ability to move easily from onecomputer system to another. The ability to run the sameprogram on many different systems is crucial to World WideWeb software


8/15

Java is distributed : D istributed computing involvesseveral computers on a network working together. Javais designed to make distributed computing easy with

the networking capability that is inherently integratedinto it. Writing network programs in Java is like sendingand receiving data to and from a file

Java is secure : Java is one of the first programminglanguages to consider security as part of its design. The Java language, compiler, interpreter, and runtimeenvironment were each developed with security inmind

Java is robust : Robust means reliable and noprogramming language can really assure reliability. Javaputs a lot of emphasis on early checking for possibleerrors, as Java compilers are able to detect manyproblems that would first show up during executiontime in other languages

Java does not work in Firefox 3.6

Starting in Firefox 3.6 you need the new Java plugin (which enableapplets to be run in Web browsers ) that is included in Java 6 Update 10and above. If you are using an older version of Java, you will need toupdate your Java plugin

Java applet causes backwards or jumbled typing in text boxes

Sometimes running a Java applet during the browser session can causethe cursor to behave erratically when you type in a text field, so that yourtext will display backwards or jumbled. Additionally, you may not beable to copy text to the clipboard. If you are having these problems, exitFirefox completely (or restart the computer) and then reopen Firefox

Java on Windows Vista

Older versions of the Java Runtime Environment may cause Firefox to hang.To resolve the issue, download the latest version of the Java RuntimeEnvironment (JRE) from Java.com and manually install it

M emory use

All versions of Java can consume large amounts ofmemory, and JRE 5 versions may use substantially morememory than JRE 6. If you are concerned about highmemory usage, update Java to the latest available version

Java applet causes Firefox process to remain in memory

When you close Firefox after running a Java applet, Firefox mayremain in memory. When Firefox is restarted, a CloseFirefox dialog may appear, including the following message :

Firefox is already running, but is not responding. To open anew window, you must first close the existing Firefoxprocess, or restart your system

P erformance Java can be perceived as significantly slower and more

memory-consuming than natively compiled languages suchas C or C++

Java plays an important role in the business environment. It hasapplication scalability. Application scalability enables the success of abusiness. Java technology has the following advantages : D ata integrity,Availability, Scalability, Manageability

Java is used in a variety of computing platforms from embedded devicesand mobile phones on the low end, to enterprise servers andsupercomputers on the high end. Java is nearly everywhere in mobilephones, Web servers and enterprise applications, and while less commonon desktop computers

The Internet has brought an important positive change to theentertainment and advertising industry. Advertisements can reach themasses within seconds over the Internet. The entertainment media hasprogressed only because of the advancements in java technology

The digitization of information has made it possible for us to store it in acompact form. D igitization enriches the quality of information storage.D igital voice and digital images are of a higher quality. D igital camerasand digital television provide their users with an enriched picture quality,thus bettering their experience with java technology

Cellular communication has revolutionized thecommunication industry. The conventionaltelephone, also a piece of java technology, was oneof the earliest technological developments incommunication. Mobile phones have broadened thehorizons of communication by enabling convenientlong-distance calling

Satellite communication is another importantdimension of java technology. Satellite TVs andsatellite radios have eased the broadcasting ofevents across the globe

These were only a few of the fields influenced by java technology. It is almost impossible to enlist allthe positive effects of java technology on society.This was just a glimpse of the real big picture
