What is Java (Programming Language)
Created by Sun Microsystems' Green Team, and originally launched as “Oak”, Java programming has become an integral part of the internet, and hand-held devices such as cellphones and game consoles. Because of Java technology, applications are faster, more intuitive, and a lot more fun to use. Although most people outside of the IT world would not recognize the name Java, nor have any idea of its existence, the truth is that Java programming was revolutionary, and brought together digital devices and the internet. What is most incredible and utterly surprising to many is that today's world could probably not operate without Java!
Before we go further in providing a definition of Java and its range of uses, it should be noted that Java programming and JavaScript are not the same. JavaScript was made by Netscape and is generally a snippet of code executed through an html page. Java can function as a stand-alone application. Other than a similar name, there is nothing similar about the two languages.
Technically speaking, Java is considered “object oriented programming” (OOP) where “objects” are the functions and commands. For example, a Smart Card when swiped must perform a set of functions. The expiry date must be checked, the balance or limit on the card reviewed, a PIN verified, checked to determine whether it has been reported stolen, and then once those jobs are completed, it must process a new transaction. All of this must be completed accurately and in lightning fast speed. Java makes this all possible.
Because of the versatility and broad reaching features of Java, there are millions of developers around the world. And they are finding new ways to use the technology everyday from medical devices to car navigational systems, lottery machines, and parking garage payment boxes. Each part of the code is an entity on its own but when placed together with other code, it becomes something else. This makes the code portable meaning it can be used for other purposes. An example of this concept is car manufacturing. Tires, seats and engines can all be used independently to mean one thing. But when assembled together as a vehicle, they mean something entirely different.
The beauty of Java is it can run on any platform. It is not restricted to is own system. This means that new operating systems, new web browser development, desktop clients, games, and millions of other applications can be built with Java in mind. In a way, Java is the standard. These things cannot be built without understanding how Java interacts with them.
Given the speed at which functions are processed, and the endless myriad of uses, it is no wonder that e-commerce has advanced in leaps and bounds. With the power of Java, small businesses have the same opportunities as major corporations with significant resources. Java has brought everything closer to the people. Someone on one side of the world can chat with someone on the other side; bank customers can calculate their own mortgage payments and interest due; credit cards can be processed over the internet in an expedient and efficient manner; and users can stay connected through an ever-growing selection of handheld products. And for those just looking for another form of entertainment, Java changed gaming, too.
Without doubt, JAVA has taken this world into the next century!
