Develop Java Website

Many web designers, once they've mastered basic web design, decide to move on to more advanced internet programming by learning how to develop Java website applications.

How to Develop Java Website Applications

Java is an advanced programming language, much like C++ or Visual Basic. However, what makes the language so unique is its portability. That is, it was designed to run independent of platform. This means that if you write a Java application, it will run on a Windows PC, a Unix workstation, or a Mac.

Java and the Internet

This portability has made Java the language of choice for Internet applications. Since Internet travelers use a browser to access the internet, Java can run inside a Java Runtime Environment (JRE) or Java Virtual Machine (JVM), which gets downloaded only once by the browser the very first time a user attempts to run a Java application. After the environment is installed, any website running Java apps will work.

What Java can do for a Website

When a web designer decides to make use of the power of Java on a website, it opens up a whole new world of interactive possibilities. The following are a few examples of the kind of Java applications that have been used on websites across the Internet.

  • Calculators for loans and mortgages
  • Embedded online games
  • Real-time chat rooms
  • Interactive maps
  • Customer forms and database processing
  • Corporate financial applications
  • Industrial real-time display of manufacturing equipment

The list of potential uses for Internet Java applications is limited only by the creativity and programming ability of the Java developer.

Learning Java takes time and patience. It certainly helps if you already know other programming languages, but it isn't necessary. By reading tutorials, attending a college class, or taking an online course, you'll be on your way to developing your own Java applications in no time.

The Structure of Java

The Java language consists of three types of programs that you can write. These are full applications, applets, and servlets.

  • Application: A Java application is a full standalone application that can run on a computer regardless of network connectivity to a server or the Internet.
  • Servlet: A Java servlet is a Java application that handles server-side processing of Internet or network requests from client computers. Servlets don't use a graphical user interface (GUI) since they typically only process information.
  • Applet: A Java applet is the Java application that runs in an Internet browser and presents the user with the GUI. Applets typically "talk" to servlets on the server in order to extract data from a database or a similar function.

The basic skills you learn, when you initially learn how to develop website java applications, includes how to create a graphical user interface, how to process data from the interface, how to read and write from data files and databases, and how to transfer data between the user and the server.

Where to Learn Java

There are three general resources available to you if you would like to learn Java. This includes a University or Community College course, an online tutorial, or an online course.

  • College course: Taking an in-person college course will provide you with hands-on practice with the Java language, and you'll have an instructor who you can immediately ask any questions that arise. College courses are usually the most expensive, but you will also receive more guidance while you are learning Java. According to the USNews 2009 list of "Best Colleges," the top rated computer engineering schools in the nation include Rose-Hulman Institute of Technology (Terre Haute, IN), Cal Poly (San Luis Obispo, CA), Harvey Mudd College (Claremont, CA), Cooper Union (New York, NY), and San Jose State (San Jose, CA).
  • Online course: If you don't have time to sit in a classroom, but still want to take a full Java course, online courses are becoming a very popular choice. Many of the nation's colleges are now offering full online degrees, and they almost all offer Java classes. A few of the top examples include CBT Direct, Penn Foster Career School, and the University of Phoenix.
  • Tutorials: If you lack both time and money, but you have the ability to easily pick up new languages from books or tutorials, then you're in luck. High quality tutorials are located throughout the Internet. Sun, the creator of the Java language, offer their own list of tutorials. Countless other tutorials, both free and paid, are available by searching for "java tutorials."

Final Notes

Learning Java can be difficult at first. But once a web designer has the entire Java toolkit under his or her belt, the potential to create a first-rate interactive website is unlimited.The following articles provide additional web programming resources:
