This course is intended for programmers who are interested in adding Java to their skills.

This course focuses only on the basics of Java Programming and provides lots of hands-on experience writing Java code as the foundation for future Java training. This course assumes that if students require a detailed introduction to Java Enterprise technologies they will take another course on Java Enterprise. If students require an introduction to Java Enterprise but will not be taking another course on Java Enterprise the following course may be more appropriate. The following course provides an introduction to Java Enterprise but does not contain the "project" featured in this course.
