Sun Java is an extremely powerful programming language that can be used to develop websites, network computers, streamline processes, within a secure environment. It is also a language known for its usefulness across many different platforms and systems. In layman's terms, that means that data written in Java performs exactly the same whether you are using Linux, a Macintosh or a PC. It is an extremely useful tool in building websites to ensure that every viewer has the same experience, no matter what kind of machine they have.

Most web designers fluent in Sun Java can use their skills to produce websites that load even complicated or large graphics quickly and without errors, a pet peeve for many computer users with a Mac as opposed to a PC. Such skills are extremely useful in seeking a career as a web designer. Java can be used to build an intranet, a web resource that is only accessible from computers within a certain network. It is very useful for maintaining security while allowing users within the network full access. Most companies with a network are looking for qualified programmers. As a student earning your Sun Java certification, expect to learn all about JSP files, Servlets, EJBs, Struts, Web Services, Server administration, and specialized programs like WebSphere or WebLogic. You will need to call on all of this knowledge if you plan on becoming an in-demand web designer.
