Mastering Java: Concurrency and Multithreading

Java

Welcome back to our Java series! In the previous article, we explored Java’s Input/Output (I/O) operations. Now, let’s dive into Java’s concurrency and multithreading capabilities, which allow you to execute multiple threads simultaneously for better performance and responsiveness.

Concurrency and multithreading are powerful features that enable Java applications to perform multiple tasks at the same time. This is crucial for developing responsive and high-performance applications, especially in a multi-core processing environment.

1. Understanding Threads

A thread is a lightweight subprocess, the smallest unit of processing. Java provides built-in support for multithreading, allowing you to create and manage multiple threads in your application.

Creating a Thread:

There are two ways to create a thread in Java:

• By extending the Thread class.
• By implementing the Runnable interface.

Example by Extending the Thread Class:

class MyThread extends Thread {
    public void run() {
        for (int i = 0; i < 5; i++) {
            System.out.println(Thread.currentThread().getName() + " - " + i);
        }
    }
}

public class ThreadExample {
