Fast Track to Java 7 and OO Development

Request more details:

This is a 5-day course that provides a broad and deep introduction to Java for non-Java programmers. The course covers all the basic concepts of Object-Oriented Programming and Java. Included is the material and labs on all the key OO concepts, including topics like encapsulation, composition, and inheritance. It also includes some coverage of advanced Java capabilities such as JDBC/JPA and the Collections Framework, as well as coverage and usage of many of the newer capabilities in Java 7. There are a large number of labs, and all labs except the first are done with a development environment (e.g. Eclipse or RAD). The lab instructions include detailed directions on the particular environment for that version of the course.
Previous programming experience in C, C++, or C#®, and some knowledge of basic object-oriented concepts are recommended.
