Java is most admired language today if we talk about the project and application development point of view. The main reason behind the popularity and success of this language is that it has three main features namely
Cross platform compatibility
The three mentioned feature which are the complex need for any application developed today wither that be a system application, mobile application or a short program that runs washing machine. Its easiest and simplest programming technique which let the user grasp it very nicely and get the result very easily has made it popular.
Java technology was first developed by a programmer named James Gosling In year 1995 as a project. Java was developed under the umbrella of Sun Microsystems limited which is now a subsidiary of Oracle corporations. Java web Programmer can compile the program with JIT compiler and then the byte code is obtained. These byte codes are platform independent and need different kind of JVM for different machine for example a java program which is written on windows platform is compatible with Linux but what changes is the environment in which this program has to run which is JVM. So Different JVM for different machine let the program run successively which is written on any of those platforms.
Java’s mostly used editions are J2SE java standard edition and J2ME java mobile edition. J2SE is used for development of industrial projects whereas J2ME is used for application development on mobile by use of swing AWT and java applets.
The way java isolates the data from the program that is using the data is called encapsulation and is the most important factor improving java security feature. When the user interacts with java applets the data those are used by application are only accessible in JVM and not to the systems so this way it secures the systems from viruses to be downloaded. Another most important feature is the re usability of code, by the mean of packages in java it is very much easy that a module can be used by many programme just by including the package that consist the module.
