Java Thread Creation & Lifecycle Explained from Scratch | Java Full Course #48

In this video, we take a deep dive into one of the most important concepts in Java — THREADS.

If you've ever been confused about:
- What exactly is a thread?
- How threads are created in Java
- What happens internally when you call start()
- How thread lifecycle actually works

Then this video will give you complete clarity from first principles.

We are not just writing code — we are understanding how Java executes multithreaded programs at a system level.

━━━━━━━━━━━━━━━━━━━━━━━
What You’ll Learn:
━━━━━━━━━━━━━━━━━━━━━━━
✔ What is a Thread (conceptual clarity)
✔ Thread vs Process (real understanding)
✔ Creating Threads using:
- Thread Class
- Runnable Interface
✔ Difference between start() and run()
✔ Can a thread be started twice?
✔ Thread Lifecycle in Java:
- NEW
- RUNNABLE
- BLOCKED
- WAITING
- TIMED_WAITING
- TERMINATED
✔ How threads actually move between states

━━━━━━━━━━━━━━━━━━━━━━━
Why This Matters:
━━━━━━━━━━━━━━━━━━━━━━━
Multithreading is used everywhere:
- Web servers
- Backend systems
- Real-time applications
- High-performance systems

Understanding threads deeply is the foundation for mastering:
→ Concurrency
→ Synchronization
→ System Design
