Java is a computer software product that allows application software to be used on a variety of platforms. It began as a project at Sun Microsystems in 1990, was rolled out to the internet in 1994 and finally became available in the General Public License in 2006. Since its first version, the platform has evolved through many changes in its usability, its language and its purpose.
In 2006 Sun Microsystems claimed that Java could be found on over 700 million personal computers around the world. That number has likely grown exponentially by now, as according to Wikipedia there are well over one billion personal computers in use worldwide. It is run on a Windows based system, but Java Runtime Environment is not included with Microsoft software. Apple has included it with their operating systems as far back as OS X, but that may change. Linux operating systems include a free version as well. Aside from assisting with operating systems, Java applications are popular with desktop programs as well. File sharing clients use it to enable a more user friendly interface, as well as the MATLAB environment. It is also a great way to make opposing programs speak to each other. For example, Lotus Notes requires access to different applications for its main purpose and Java helps them all talk to each other.
Mobile phones are not simply mobile phones anymore. They are messaging systems, browsers, organizers, and data carriers. For all the vital applications to speak to each other, a software package such as Java Platform Micro Edition (ME) is used. With all the competing mobile manufacturers vying for business with diverse new mobile units, a basic standard for programs to run was needed. In April 2001 the Mobile Information Device Profile (MIDP) was introduced. The specifications are specifically for the use of Java on devices with software embedded on them, i.e. mobile phones. MIDP uses the Java ME framework, and thus us a vital part of making your phone applications work with each other.
Internet technology goes hand in hand with the platform, and will likely never let go. A web server armed with the platform has created the extremely interactive online environment we now know as the internet. Entire businesses can now be moved online and offered to a wider client base, all because the interface is dynamic and easy to use. Additionally, the platform is widely used for building software tools for highly specific cases. Internal application servers and large databases for specific enterprises such as a medical records database, will use Java as a platform so that multiple users can access the information with a variety of programs.
Java is used in such a broad spectrum of ways that it is hard to think of a technical application where it cannot be useful. Plus, as companies small and large take on more IT tasks internally, the need to speak the language is vital. No longer can one just read the 'Java for Dummies' and expect to build robust web applications that remain effective. Continuous training on all the current versions, additions and developments is imperative. If you are a beginner, then start with a self-paced online beginner course and move on from there. It will take about 12 to 18 months to learn Java, just as with any high-level programming language. Have a purpose for your training. Even experienced programmers will set a task and then learn the tools they need to complete the task. It helps to visualize how you will use the information you are learning. Go to the library, talk to people who know about Java, as questions. Practice. Learning a new language takes practice, so don't be afraid to try some platform building on your own.
