Please keep making these videos forever. They are wonderful for sending to junior developers who haven’t learned these things yet. You must have the most comprehensively “correct” fundamental Java tutorials on YouTube. Case in point, your use of a synchronized set and a countdown latch here. They are not core to what you are teaching, but you use them anyway. I think most Java demos would use a HashSet and an int there, and it would likely work in a synthetic demo environment, but would yield insidious bugs in real life concurrent use. Thank you for your efforts.

Man. These videos are just wonderful. I’m a junior developer who has desperately been trying to get better at concurrency and distributed systems. There really is a select few people breaking things down like this. Perfect mix of theory and practical knowledge. Thank you!

for m=1 to infinity
Thanking you for Explaining the concepts so Amazingly

[ShivSinghSengar]

Gr8 way of explanation better if I had visited here than reading concurrency in practice first

[ShrinathKuppa]

Thank you for this video. Really helps understand the concept better!
