Java is a dynamic programming language used for servers, mainframes, and big picture systems. It has various incarnations, including Java 2 Platform, Standard Edition (J2SE), which is mainly used for writing applets and other applications. J2SE is an amazing web business promoter and allows the development of JavaBeans, which are reusable applications that can be easily developed and assembled to create more sophisticated applications.
One of the most dynamic programming languages used by computer programmers today is Java. This language has advanced over the years in both functionality and scope. Current editions are on the Java 2 platform, which is, not surprisingly, the second major incarnation of Java software. It also has various incarnations, including Java 2 Platform, Standard Edition (J2SE). J2SE is mainly used for writing applets and other applications.
Especially in the case of servers, mainframes and big picture systems, Java makes business processes happen. Technically and historically, it is the creation of Sun Microsystems, a computer company that produces both hardware and software. Other companies now create Java applications, but Sun was the first.
A well-known type of Java application is the applet, a kind of fast subroutine that is largely platform-independent and can run within other frameworks. Applets are mini applications that perform a variety of functions, large and small, mundane and dynamic, within larger applications. Technically, an applet is like a lite application, as the name suggests. A software developer skilled in developing applets is in high demand.
A great example of an applet is a browser-based plug-in, such as one that allows users to view Flash® movies or listen to audio files by clicking on a link on a web page. This click keeps the user in the browser environment , simultaneously launching the application within an application which is the applet, showing the requested video or playing the requested sound. Many online games are also based on applets.
The Java 2 platform has three basic editions: Micro, Standard and Enterprise. They have an increasing amount of features and flexibility, with the Micro Edition being used for small applications and the Enterprise Edition being used for large server-based functions. In between is the Standard Edition, or J2SE, which has applications up and down the requirement ladder, catering to the needs of both individual and complicated users.
One of the primary uses of J2SE is the development of Java applications for individual computers. The web-based business sometimes lives and dies on the successful integration of applets into e-commerce and other web-specific functions. J2SE applets and other applications make these functions run smoothly; without them, many transactions and other interactions on the Internet would not take place. In this way, this edition is an amazing web business promoter.
Another important feature made possible by this incarnation of the language is JavaBeans. These are reusable applications that can be easily developed and assembled to create more sophisticated applications. Basically, they are the building blocks of custom applications. Java may be the underlying technology, but JavaBeans are what really click the functionality and individuality of J2SE.
