    Multithreading is the ability of a program to execute multiple threads concurrently within the same process. A thread is the smallest unit of execution, and multiple threads can share the same memory space while running independently. This approach improves CPU utilization, speeds up execution, and keeps applications responsive.

    In contrast to multiprocessing, where each process has its own memory space, threads share the same address space, making data sharing easier but also introducing risks like race conditions if not synchronized properly.

    Creating Threads in Java

    There are two primary ways to create threads:

    • Extending the Thread class

    class MyThread extends Thread {
    public void run() {
    System.out.println("Thread is running");
    }
    }
    public class TestThread {
    public static void main(String[] args) {
    MyThread t1 = new MyThread();
    t1.start(); // starts the thread
    }
    }

    • Implementing the Runnable interface

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

    What is multithreading & how does it work?
    In simple terms, multithreading means running multiple “threads” of execution within a single program. A thread is like a small, independent path of execution. Think of a thread as one person doing a task: if you have multiple threads, it’s like having several people working together on different parts of a job.
