Java has revolutionized the world of Information Technology since its release in 1995 by Sun Microsystem. It has become the core competency of Sun Microsystem. The language derives most of its syntax from another very popular language C and C++. To run program the system needs to have JVM i.e. Java Virtual Machine. The JVM converts a program to bytecode and then runs the file irrespective of the computer’s operating system. This is the convenience that this language provides. A program written in his language can be compiled and executed on any computer system irrespective of the one on which It is written. This called the cross platform functionality.
It has proved itself to be one of the most popular languages mainly for client server based applications. The client server applications are those that require the interaction of the application with web web services and networks. This is because the programs written in it have the ability to interact with servers and networks that provides a real time flow of information. This ability of this language has turned to be very useful or business these days. The reason for the rise of online business communities is only because of the. It has provided a boom in the eCommerce industry. It provides the websites and applications the ability to interact with the network. This facilitates the online payments and provide the convenience to the customers.
The technical language has established itself as one of the most favorable platforms for developing websites and software. One of the most interesting facts about this language is that the Java application development process a take place in the modules. It means that the developers can write the program in modules which can be integrated later on to create the full program. The benefit of this feature is that now if someone wants to have a website or a program with several functionalities but the particular programmer does not possess the necessary expertise than the whole website or program can be broken into different modules. These modules can then be developed in different locations by different developers but can be integrated later on.
One more benefit that this module feature provide is that the debugging can be done module wise. So when the modules are integrated later on the final program or website will be bug free. The modules are also known as Classes. These modules or classes are developed in such a way that they can be reused later on. For example if there is a travel booking website that needs to be developed so It must be having the online payment functionality. So while writing the codes the developer develops a separate module for online payment functionality. This module then can be utilized later on if any website or program with similar functionality needs to be developed. These modules can not only be reused but can be modified according to the requirement. The codes can be extended as well as modified.
It has one more amazing feature which is an automatic garbage collection. In this the Java developers create different objects. These objects utilizes memories during runtime as well as when they are not in use or even when their role in the program is over. So Java runtime is responsible for identifying such programs and removing them. This ability of this technology provides access to at the memory which is otherwise not accessible by any other method. The garbage collector can run anytime but mostly it run’s when the program is ideal. The garbage collector runs itself when it analyzes that there is no free memory to be allocated a new object. This free’s up the memory and decreases the load on the system which intern improves the computing capabilities of the system.
It provides the safety and security feature too. It works like if anyone is transferring the Java codes from one system to other then those codes will be scanned automatically before being saved on the system to which they are being transferred to. Even if the code is saved it will never be executed if it will be having a single bug or virus. This is object oriented programming language which means the programs are written keeping objects in mind. All codes of these are written in objects and classes. It is architecture wise neutral which provides it the portability. The portability means that the program can run on any hardware or operating system. In C/C++ the portability issues arises due to fact at the source codes run in different ways because different hardware compute arithmetic calculations in different ways.
The Java has revolutionized the world of Information Technology by the indispensable features it provides. These features have provided the ease of programming as well as the convenience to both the developers and the end users. It has many features that it has derived from languages like C and C++ . It does not use pointers and storage classes that add to the complexity of the program. It is therefore simple with lots of features.
