Java Programming

Course Code - PE-201 Duration - 4 Days

This 4 day course is designed for those wishing to learn the Java programming language. This course is a primer for more advanced Java courses. The emphasis is on the Java language and the core APIs. It covers the new features introduced in Java 5. The practical exercises constitute about 50% of the course time. They use console applications rather than graphical applications to gain familiarity with Java. Graphics is a large subject which is best left to a more advanced course.

Prerequisites

This 4 day course assumes knowledge of the basics of the C-like family of languages, such as C, C++ or C#. If you do not already have this knowledge, then there is a 5 day version of this which spends more time on the Java language and has additional exercises to gain familiarity with the Java programming constructs.
