Is this course right for you?

Our take
A thorough, up-to-date way to learn Java from zero, and highly rated. With over 900,000 students it is one of the most-taken Java courses on Udemy.

Good for: complete beginners who want a thorough, up-to-date Java course.

Skip if: you already know Java, or you want a short, focused refresher.

Tim Buchalka takes you from data types and control flow through object-oriented design, collections, lambdas, concurrency and JDBC, kept current through Java 17's long-term-support line rather than chasing every release. You reach employable core Java well before the end and use the rest as reference.

It is enormous, so it is not a quick refresher, and it does not go deep into specific frameworks like Spring or Android — it is the language, not the ecosystem. If you already know Java, skip it. On price, wait for a Udemy sale rather than paying the sticker.

Frequently asked questions

Yes. Tim Buchalka has maintained it since 2016, and it now teaches Java 17 with older versions covered too and newer features added over time. Java's core changes slowly and carefully, so the fundamentals you learn stay valid across recent releases — you are not learning something that will be obsolete by the time you finish the many hours of material.

Yes. It starts from installation and basic syntax and assumes no prior programming, then goes a very long way. The real challenge is its sheer length, so beginners should follow it in order and resist the urge to skip around, treating it as a structured path rather than trying to absorb a hundred-plus hours at once — steady progress beats bingeing here.

Treat it as a reference you work through, not a race to the end. The instructor himself notes you can reach employable basics in the first stretch, then dip into the later, more advanced sections as you actually need them. Coding along and doing the challenges matters far more than watching every hour — passive playback of a course this size is where motivation quietly dies.

Only modestly. A Udemy completion certificate is not an industry credential and rarely sways employers on its own. What genuinely helps is the actual Java skill you build and the projects you can create and show with it. Focus your energy on becoming able to build things in Java; the certificate is a byproduct, not the reason to take the course.

It is a paid Udemy course, almost always available at a steep discount during Udemy's regular sales rather than at full price, so most people pay a small fraction of the list figure. Buying it gives lifetime access, which suits a course this large — you can return to advanced topics months later, long after you first worked through the basics.
