Introduction to Multithreading in Java 🔄

Multithreading is a crucial feature in Java that allows concurrent execution of two or more parts of a program to maximize CPU utilization. Unlike process-based multitasking, thread-based multitasking enables efficient task execution within a single program.

Why Multithreading? 🤔

• Better CPU Utilization: Multiple threads can run simultaneously, preventing CPU idle time.
• Faster Execution: Tasks that can run concurrently execute more quickly.
• Improved Responsiveness: Applications remain responsive while executing background tasks.

Real-Life Example 🏃‍♂️📞

Think of a mobile phone: you can browse the internet while downloading a file and receiving notifications. These tasks run as separate threads, improving efficiency!

Creating Threads in Java

Threads in Java can be created using two primary methods:

1. Extending the Thread class
2. Implementing the Runnable interface

Example: Implementing Runnable

class MyThread implements Runnable {
    public void run() {
        System.out.println("Thread is running...");
    }
    public static void main(String args[]) {
        Thread t1 = new Thread(new MyThread());
        t1.start();
    }
}

Conclusion 🎯

Multithreading is essential for modern applications requiring concurrency. Understanding how to implement it efficiently can lead to performance improvements in Java applications!
