Java Technology: Understanding and Use

Since its first implementation in 1995, Java has become quite well known. The popularity of Java is such that almost everyone has already, in some form or the other, been introduced to it. It might have been through some social application like a website chat or a game or even banking. It is the most important part of corporate computing nowadays. Java itself was designed to be easy to use, straightforward to write& compile and its implementation is quite simple as well.

Java runtime automatically assigns memory usage, and recovers memory when objects are no longer referred to or are in use. This makes Java a much easier language to use than something like C or C++ which requires the programmer to manage memory allocation within the program itself. Over the years Java has been tested, refined and extended, and has been approved by a dedicated community. Currently there are more than 6.5 million developers.

Java has become invaluable to developers because it allows them to write software on a single platform and run it virtually on any other platform due to a deliberately high degree of portability across systems and hardware. There are many pieces of hardware, from computers and mobile phones through to parking meters, etc  which you will no doubt use on a daily basis and which are driven by Java applications. The range of uses to which Java has been put is truly staggering, and it is this breadth of implementation that has put Java developers in such high regard and demand.

Some advantages of JAVA:

• It is an open source  Platform independent
• Java API’s can easily be accessed by developers
• It supports garbage collection, so memory management is automatic
• It always allocates objects on the stack
• It can embrace the concept of exception specifications
• Multi-platform support language and support for web-services
• Using JAVA we can develop dynamic web applications
• It allows you to create modular programs and reusable codes.

Although Java has been highly criticized as a scripting language it has still emerged as the most popular language when it comes to developing apps. It has been widely used in language in programming and in the year 2005, a new development was seen within the language. The language can be used with free tools such as Linux, which can execute Java apps.
