What is multithreading in Java

Multithreading in Java is a programming concept that allows for the concurrent execution of two or more threads within a single process. Each thread can run independently and performs tasks concurrently, which helps in improving the performance of applications by utilizing CPU resources more efficiently. Java provides built-in support for multithreading through the Thread class and the Runnable interface, making it easier for developers to implement concurrent programming.

Using multithreading, Java applications can handle multiple tasks simultaneously, such as handling multiple user requests in a server application or executing background tasks in a user interface without freezing the GUI.

// Example of a simple multithreading in Java class MyThread extends Thread { public void run() { System.out.println("Thread " + Thread.currentThread().getName() + " is running."); } } public class MultithreadingExample { public static void main(String[] args) { MyThread thread1 = new MyThread(); MyThread thread2 = new MyThread(); thread1.start(); // Starting thread1 thread2.start(); // Starting thread2 } }
