Explain what is meant by multithreading in programming and what advantages it provides.

Multithreading in programming is the ability to execute multiple threads (parts of a program) simultaneously within a single process. In Java, each thread represents a separate sequence of execution that can run in parallel with others.

Advantages of multithreading:

• Increased performance through parallel execution of tasks, especially on multi-core processors.
• Improved responsiveness of applications, for example, in a graphical user interface, the user can continue interacting with the program while other tasks are running in the background.
• Efficient resource utilization, allowing input/output operations and computations to be performed simultaneously.

Example of creating and starting a thread in Java:

class MyThread extends Thread {
    public void run() {
        System.out.println("Thread started");
    }
}

public class Main {
    public static void main(String[] args) {
        MyThread thread = new MyThread();
        thread.start(); // Starting a new thread
    }
}
