This course introduces you to the Java programming language, and its Internet and intranet use.

The course starts with an introduction to the terminology and structure of Java, so that you know your applet from your servlet, and the difference between a JSP, a JVM and a JRE. We then go on to cover the fundamentals of the Java language - comments, compiling, variables, constants, statements, declarations, conditionals, loops, arrays, etc.

Java is an object oriented language; the course briefly covers the principles of object orientation before it goes on to cover the definition and creating of classes of objects, and the use of standard classes. We look at static and dynamic methods, extending classes to create subclasses via inheritance, polymorphism, overloading ... as well as constructors, destructors, inner classes and much more.

It's important that you manage your design and code in an object oriented language, and the course moves on to briefly introduce design principles, such as UML, before spending rather longer on Java-specific topics such as packages, beans, levels of access to variables, jars, classpaths, and so on.

Handling text through string objects, and using standard collection objects such as vectors, stacks and hashtables is covered once you have a good grounding in how Java's objects work. We also cover input, output and exception handing in some depth on this section of the course. Threads, serialisation, synchronisation and internationalisation will also be overviewed.

If you're going to be writing Java applications to run on a web server, you'll need to know about servlets and probably JSP as well; the course goes on to cover those subjects, giving you the opportunity to write practical examples to have a Java program look up information for Web presentation from a server-based resource. For effective displaying of information, Java can also run as an applet in your browser, and we'll show you how to generate graphics through standard tools such as the AWT and swing classes.

The course concludes with a section on resources that are available, and a forward-looking lecture that overviews many more of the facilities available in Java, and what they can do for you.

Practical experience in programming in another computer language, such as C, C++, Visual Basic, JavaScript, Fortran or Perl

The Java language is now firmly established in a wide variety of applications, with an incredible range of facilities and options available to go with it. One of the most common uses of Java programs is on a web server, where "Servelets" or "JSP"s provide the logic behind web based applications from banking to weather forecasting, and from government sites through scientific research.
