TUTORIALS POINT Simply Easy Learning Java Overview J ava programming language was originally developed by Sun Microsystems which was initiated by JamesItalic text Gosling and released in 1995 as cor e component of Sun Microsystems’ Java platform (Java 1.0 [J2SE]). As of December 20 08 , the latest rel ease of the Java Standard Edition is 6 (J2SE). With the advancement of Java and its widespread popularity, multiple configurations were built to suite various types of platforms. Ex: J2EE for Enterprise Applications, J2ME for Mobile Applications. Sun Micro systems has renamed the new J2 versions as Java SE, Java EE and Java ME , respectively. Java is guaranteed to be Write Once, Run Anywhere . Java is:  Object Oriented

In J ava , everything is an Object. Java can be easily extended since it is based on the Objec t model.  Platform independent

Unlike many other programming languages including C and C++ , when Java is compiled, it is not compiled into platform specific machine, rather into platform independent byte code. This byte code is distributed over the web and interpreted by virtual Machine (JVM) on whichever platform it is being run.  Simple

Java is designed to be easy to learn. If you understand the basic concept of OOP

,J ava would be easy to master.  Secure

With Java's secure feature , it enables to develop vir us - free, tamper - free systems. Authentication techniques are based on public - key encryption.  Architectural - neutral

Java compiler generates an architecture

- neutral object file format , which makes the compiled code to be executable on many processors, with th e presence of Java runtime system. 

eing ==== architectural - neutral and having no implementation dependent aspects of the specification makes Java portable. Compiler in Java is written in ANSI C with a clean portability boundary which is a POSIX subset .  Robust

Java makes an effort to eliminate error prone situations by emphasizing mainly on compile time

error checking and runtime checking.  Multithreaded

With Java's multithreaded feature , it is possible to write programs that can do many tasks simultane ously. This design feature allows developers to construct smoothly running interactive applications Bold text'
