Java Core | How HashSet works internally?

Watch at 1.5x speed or above. 💡 Note: I am constantly trying to improve my teaching and technical clarity. If you feel I’ve missed a nuance or if you have a better way to explain this, I’d love to hear from you in the comments. As a Java Engineer with 3.5 years of industry experience, I’ve realized that the best way to master a concept is to explain it. These videos serve as my personal "video-notebook"—a place where I break down Java concepts and interview patterns to ensure I never forget the logic behind them. Why I make these: To apply the Feynman Technique (Teaching = Mastery). To create a quick revision library for my future self and interviews. To share real-world engineering perspectives with fellow developers. If you find these notes helpful for your own journey or interview prep, feel free to stick around! If you see a way I can improve an explanation or if you have a different perspective, please share it in the comments—I believe in constant learning.
