Hands- on Learning: Throughout the course students will be led through a series of progressively advanced topics, where each topic consists of lecture, group discussion, comprehensive hands-on lab exercises, and lab review. This course is "skills-centric", designed to train attendees in essential object oriented, Java & JEE development skills, coupling the most current, effective techniques with the soundest coding practices.

This course is about 50% hands-on lab and 50% lecture, with extensive programming exercises designed to reinforce fundamental skills and concepts learned in the lessons. Our courses include ample materials and labs to ensure all students are either appropriately challenged, or assisted, at all times - no matter their skill level.
