Paid Udemy video courses include a certificate of completion when you finish; free courses and practice-test-only courses do not. It shows you did the work, but it is not an accredited qualification. Coursera and edX usually charge for a certificate, issued with the university or company that made the course. LinkedIn Learning gives a certificate of completion for most of its courses as part of the subscription.

Java Masterclass 2025: 130+ Hours of Expert Lessons
A 136-hour, 739-lecture Java course from Tim Buchalka, refreshed in August 2026, that nearly a million students have used to go from zero to solid core Java.
Best for: People who want one long, structured Java course with 50 coding exercises and are prepared to spend months on it.
-
- Covers core Java end to end: OOP, generics, lambdas, collections, streams, file I/O and concurrency in 21 sections.
- 50 coding exercises and 50 quizzes, plus source code attached to every video, which beginners call guard rails.
- Updated in August 2026 and refreshed steadily since 2015, so the Java 17 material is current.
- Experienced developers in the reviews say they still picked up new things from it.
-
- Low-star reviews say examples are overcomplicated, with several classes introduced at once instead of simple demos.
- Code is pasted onto the screen rather than typed live, and some find the newer videos rushed and monotone.
- At 136 hours it is a months-long commitment, and course files arrive as many separate zips.
2

- Assignments after most modules and a trainer team that reviewers say answers questions quickly.
- Updated July 2026; covers Selenium 4 features, Chrome DevTools Protocol and a GitHub Copilot lecture.
-
- Nearly everything is built inside one project; a one-star reviewer wanted a second full build to practice on.
- 56 hours long, and the core Java tutorials sit at the end of the syllabus instead of the start.
