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 a desktop application that connects to a database via a web service
and a web application comprising Java Server Pages, Servlets and Enterprise Beans.
Each delegate has the use of a computer; course hours are 9:00 to 5:00.
Course Dates and Fee
In addition to the above public courses in London, we can provide
customised and in-house training.
Prerequisites
