In this video, we break down what actually happens inside Java, the JVM, and the operating system when create and run a thread.

👨‍💻 What you’ll learn:
• What really happens when you create a Thread object (no OS thread yet!)
• How calling start() triggers native code and OS thread creation
• How JVM interacts with Thread.start0()
• How OS allocates a new native thread + stack
• How scheduling works behind the scenes
• Why JVM calls run() internally (and why you should NOT call run() yourself)
• What happens when the thread finishes and how JVM performs cleanup

This video explains the exact sequence interviewers expect when they ask: “What happens internally when you call thread.start()?”
