Java Programming

Objectives
On successful completion of this course, attendees will be able to:

• The principal objective of this course is to enable delegates to produce programs for an object-oriented environment. These programs are designed for applications whose features include the use of files, graphical interfaces, multitasking and native environments. The course covers Java 2, which is the latest version of the Java programming language, and the Java API and features building applets and single applications.

Who Should Attend
Experienced programmers who need to be able to understand and use Java (this course covers Java 2 1.2 and 1.3).
Prerequisites
Experience in using a procedural programming language such as Cobol, ''C'', Pascal or PL/I is assumed. A knowledge of object-oriented programming or design is not necessary.
