Curso para aprender el lenguaje de programación Java y Programación Orientada a Objetos (POO) desde cero y para principiantes. 75 lecciones, más de 8 horas en vídeo y 150 ejercicios prácticos.
A beginner Java and OOP course from a Spanish-speaking YouTuber/Twitch streamer, structured as 75 lessons with matching video timestamps, source files, and exercises. It's for absolute beginners who read/understand Spanish and want a from-scratch intro to Java syntax and OOP fundamentals, not for anyone looking to build real projects.
Every lesson maps to a specific timestamped video segment and a corresponding .java file, so the material is easy to navigate rather than just a wall of markdown. Coverage of OOP fundamentals (inheritance, polymorphism, abstraction, composition, access modifiers) is unusually thorough for a beginner course and each concept gets its own file plus an exercises file. The repo is a companion to free YouTube content, not a paywalled funnel — the actual lessons are open.
Everything is in Spanish, including code comments presumably, which caps the addressable audience immediately. There's a hard upsell to a paid platform (mouredev.pro) baked into the README, and the author states outright this only covers language fundamentals, not real project structure, build tools, testing, or dependency management (Maven/Gradle aren't mentioned once). Last push was mid-2025 with no indication of a more advanced follow-up course actually shipping despite the FAQ promising one, and there's no CI, no tests validating the exercise code compiles, just static .java files.
