Duration: Two (2) Weeks
This session gives an in-depth knowledge on Core
Java. The lab sessions will stress more on teaching candidates
Object oriented concepts and designing classes. This is a two (2)
weeks course with 50 % theory and 50 % lab. No prior knowledge of
Java or object oriented concept is expected of the candidates
