Info

My name is Seán Kennedy. I have a PhD in IT and am OCA and OCP certified. I have taught the OCA/OCP syllabi since 2013 on a Masters course for a highly-regarded software company.

This channel is about helping people understand Java and also pass the Oracle Java Certification exams.

Regards,
Seán.
