Java Course

Synopsis

This comprehensive five-day course begins with an introduction to object-oriented programming in Java, progressing to cover databases, graphical user interfaces, web applications, web services and enterprise beans.

The theory is reinforced by building an application with both web and desktop user interfaces. The desktop application connects to a database via a web service, while the web application comprises Java Server Pages, Servlets and Enterprise Beans.

Each delegate has the use of a computer; course hours are 9:00 to 5:00.
