Overview

What this course is about

Over roughly 4 weeks, this Java Script course gets you doing real work early. Java runs a large share of enterprise and Android software, and strong Java fundamentals open doors across the industry.

Expect to spend most of your time actually doing the work — you’ll understand how large Java systems are structured and write object-oriented Java programs along the way.

Every session is one-on-one, so the pace bends to you — not to a class average.

By the end

What you’ll be able to do

  • Write object-oriented Java programs

Basic programming logic helps but is not essential. The first sessions make sure everyone is on solid ground before moving faster.

Every session is live and one-on-one with your instructor. Nothing here is a pre-recorded playlist you watch alone.

You’ll finish with practical work — write object-oriented Java programs — plus an Osian Academy certificate you can share with employers.
