I love this guy. So clear and uses only blackboard. Most introductory class starts out without explaining what objects, class, etc are and it took me a long time to figure it those definitions myself. Here he gives you very concise definitions right off the bat. Berkeley CS is awesome.

Great Lecturer

[6dark6alex6]

This guy is an amazing lecturer. In my experience as a computer science major, teachers either teach you NOTHING ("computers do math and stuff... ummm... yeah") or assume you know EVERYTHING. ("Just make a 3D video game. Just do it. What's the big deal?")

And the worst part is, those teachers often alternate. Meaning you are 100% and completely lost and learn little to nothing correctly.

These videos are my saviour for my data structures class, with the second variety of teacher.

@tullikulli NO. This is a Computer Science class. It is a course on Java Data Structures from UC Berkeley.

And, you're welcome.

Thank you so much for this, you are a great teacher. I study in college in Quebec and teachers didn't go that deep. Watching this playlist I revised my courses and also learned a lot more.

@IIGrudge great lecturer but many thing would be better typed and projected instead of chalked up, otherwise very very good lecturer

@007gurkan No, the string object "qwe" doesn't have anything pointing to it anymore so the garbage collector will pick it up and mark that memory location as available for writing. You have no way of getting back to that location in memory anymore without anything pointing to it.

@ducefalo21

Why? It's in clear English? Do you have any idea how long it would take to type out 50 minutes of subtitles?
