Java Training Courses in Cape Town


Java Training Package

International exam: 1Z0-803 and 1Z0-804 (OCA & OCP)

The Oracle Certified Associate (OCA) Java SE 7 now has an all new definition and focus - with certification objectives that measure not only your day-to-day programming skills, but also your ability to manage the situations you are likely to encounter on various projects. The OCA Java SE 7 certification requires successfully completing a single exam: 1Z0-803. 2KO presents Java courses in Cape Town by means of full time instructor-led training; as well as internet-accessible online training, which are aimed at International IT Certification exams. 2KO International Group provides IT & business training courses for learners of all levels, and is also a top-rated, certified supplier of online IT courses, enabling 2KO students the opportunity to study courses online world-wide, to ensure the best training possible.


The Oracle Certified Professional (OCP) Java SE 7 is a more advanced certification than ever before. It not only builds on all of the competencies incorporated into our new OCA Java SE 7 certification, but also consists of new, advanced skills required of top-performing Java programmers. As a result of its new depth, the OCP Java SE 7 certification now requires you to hold the Associate level Java certification prior to achieving your OCP credential. Certified Java Associates can pursue the OCP certification by completing exam 1Z0-804.

This entire course runs over a period of 2 weeks and focusses on both international certifcates (OCA & OCP).
