Java Multithreading Examples

This project demonstrates different ways of creating and running threads in Java, using simple Hello and Bye outputs.
It is designed as a reference/tutorial for learning the basics of concurrent programming.

📂 Project Structure

• MultiThreadingExamples.java
  Contains three approaches to multithreading:
  1. Implementing the Runnable interface\
  2. Extending the Thread class\
  3. Using anonymous classes / lambda expressions

---

🚀 How to Run

1. Compile the program:

   javac MultiThreadingExamples.java

2. Run the program:

   java MultiThreadingExamples

---

📝 What You Will See

• Multiple threads printing "Hello" and "Bye" messages concurrently.
• The order of outputs changes each run, because thread scheduling is nondeterministic.

Sample (varies per run):

=== Example 1: Runnable Interface ===
[Runnable] Hello 1
[Runnable] Bye 1
[Runnable] Hello 2
[Runnable] Bye 2

=== Example 2: Extending Thread Class ===
[Thread] Hello 1
[Thread] Bye 1
...

=== Example 3: Anonymous Runnable ===
[Anonymous] Hello 1
[Anonymous] Bye 1
...

=== All threads completed ===

🎯 Learning Outcomes

• Understand how to create and run threads in Java.
• Observe interleaving outputs from concurrent execution.
• Compare different methods (Runnable, Thread, and lambdas) for creating threads.

---

📖 Notes

• Output order may vary because the JVM and OS decide thread scheduling.\
• Thread.sleep() calls are added for clarity, to slow down output and make interleaving observable.
