Accelerated Fundamentals of FUN JAVA Programming Workshop

Class Description:

By the use of lectures, demonstrations and lab exercises , this **FUN** mini-course will introduce you to one of hottest languages around, the JAVA programming language. Unlike Java Script, this is a full-featured, strongly-typed, object-oriented, events-driven, error-handling, safe language that is platform independent and capable of running in many diverse environments, thus directly challenging C/C++ in the marketplace. Whether it be a stand-alone command line application program on a mainframe, a Javax Swing graphical application on a client, a thread running in a web server or a graphical application running as an Applet inside a web browser, JAVA is taking the world by storm. Shouldn’t you know something about JAVA?
Attendees will learn Java2/Java5 syntax, how variables, data structures, objects, functions, events and run-time errors are handled in Java. The course introduces the modern day concepts of object oriented, event driven programming in a fun, easy to understand, way, comparing constructs in Java with other programming languages when beneficial. Class lecture will be mixed with in-class and out-of-class projects to reinforce learning the concepts discussed in class.

Prerequisite:

Students should have some prior programming knowledge or experience, but not necessarily in JAVA or Java Script (for instance, Visual Basic, C/C++, or Perl would be fine). Some high level modular programming concepts and exposure to object based programming would be exceedingly helpful. Some knowledge of HTML and forms would be helpful with JSPs and Applets. Proficiency with Windows expected.

Targeted for:

This course is ideal for individuals that want to learn Java from the ground up. The class will proceed at a fast pace, allowing most individuals making an effort to learn this material, to keep up with the class. The course is appropriate for individuals wishing to learn how to write stand-alone Java programs, both text oriented command line and Javax Swing graphical applications. In addition, the course will provide an overview of advanced Java concepts such as Threads, Applets, and distributed computing concepts such as Remote Method Invocation (RMI), Java Server Pages (JSP), Servlets, JavaBeans, and possibly Jini). The class is structured to be as interactive as possible by making use of live demonstrations that review and emphasize the concepts taught in the class and assigned as homework projects.

Handouts:

Copies of the course outline slides will be provided along with relevant handouts when appropriate.
