Java Development

Comprehensive Java (Core + Advanced Java)

This comprehensive Java course covers the whole language in one journey: core Java (syntax, OOP, collections, exceptions) then advanced Java (servlets, JSP, JDBC and enterprise patterns). It's the complete foundation for backend and Android careers alike. You write real code throughout, guided one-on-one.

Overview

What this course is about

Comprehensive Java is taught here as a hands-on, live one-on-one course rather than a stack of videos. Java runs a large share of enterprise and Android software, and strong Java fundamentals open doors across the industry.

By working through real exercises you’ll understand how large Java systems are structured, write object-oriented Java programs, and build the judgement that only comes from practice.

Because it’s taught live and personally, questions get answered the moment they come up.

By the end

What you’ll be able to do

  • Write object-oriented Java programs
  • Work with collections and exceptions
  • Build small console and backend apps
  • Understand how large Java systems are structured

Questions

Before you enroll

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.

Yes. Because it’s one-on-one, sessions are booked around your availability, including evenings and weekends.
