Example of Multithreading

⚙️ 🔥 Multithreading Example in Java

✅ Goal:

We’ll create two threads:

• One prints numbers

• One prints letters
  → both run concurrently

---

📜 Java Code:

public class MultiThreadExample {
    public static void main(String[] args) {
        // Thread 1: Prints numbers
        Thread numberThread = new Thread(() -> {
            for (int i = 1; i <= 5; i++) {
                System.out.println("Number: " + i);
                try { Thread.sleep(500); } catch (InterruptedException e) {}
            }
        });
 
        // Thread 2: Prints letters
        Thread letterThread = new Thread(() -> {
            for (char c = 'A'; c <= 'E'; c++) {
                System.out.println("Letter: " + c);
                try { Thread.sleep(500); } catch (InterruptedException e) {}
            }
        });
 
        // Start both threads
        numberThread.start();
        letterThread.start();
    }
}

🧠 What’s Happening?

• Each Thread runs a separate task.

• Both threads share the CPU and run concurrently.

• Thread.sleep(500) gives each thread a little breathing room so you can actually see the switching.

🖥️ Sample Output (non-deterministic):

Number: 1
Letter: A
Number: 2
Letter: B
Letter: C
Number: 3
...

• The output order may vary each time you run it — that’s multithreading in action.

✅ Why It’s a Real Multithreaded Example

Feature	How It Applies
🚀 Concurrency	Two threads run at the same time
🧠 Shared context	Both threads run inside the same process
⏱️ Asynchronous behavior	Output order depends on OS thread scheduling
