History Of Java

Microsoft System has developed this technology known  JAVA. The technology is called DOT NET Microsoft (as on today). That is why DOT NET technology called JAVA will run on all operating system’s irrespective of their providers therefore it is called platform independent technology The slogan of JAVA is “Write One’s Reuse/Run Anywhere J2SE (Core JAVA) Notes applications, two software companies came up Sun Micro System. DOT NET and Sun JAVA. Both this technologies are known or called distributed technologies will run only on that operating system’s which are provided by technology is platform dependent technology technology. (WORA)”. and server whose Micro System has technologies. form technology. Whereas, the JAVA J2SE (Core JAVA) Notes By Mr. K.V.R Page 3 DOT NET technology is not freely downloadable where as JAVA freely downloadable.so java is a freeware. DOT NET supports Microsoft developed design patterns (general designed patterns are not supported) whereas JAVA supports all the design patterns which are available in IT. Design pattern is a predefined and proved rule by third party industry experts to avoid the receiving problems which are occurring in software development.

 History of JAVA: JAVA is a distributed technology developed by James Gosling, Patric Naugton, etc., at Sun Micro System has released lot of rules for JAVA and those rules are implemented by JavaSoft Inc, USA (which is the software division of Sun Micro System) in the year 1990. The original name of JAVA is OAK (which is a tree name). In the year 1995, OAK was revised and developed software called JAVA (which is a coffee seed name). JAVA released to the market in three categories J2SE (JAVA 2 Standard Edition), J2EE (JAVA 2 Enterprise Edition) and J2ME (JAVA 2 Micro/Mobile Edition). i. J2SE is basically used for developing client side applications/programs. ii. J2EE is used for developing server side applications/programs. iii. J2ME is used for developing server side applications/programs. If you exchange the data between client and server programs (J2SE and J2EE), by default JAVA is having on internal support with a protocol called http. J2ME is used for developing mobile applications and lower/system level applications. To develop J2ME applications we must use a protocol called WAP (Wireless Applications Protocol).
