Milliste meetoditega saab Java-s luua ja käivitada andmevoo?

In Java, there are several main methods to create and start a data stream (execution thread):

1. Inheritance from the Thread class

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

MyThread thread = new MyThread();
thread.start();

2. Implementing the Runnable interface

class MyRunnable implements Runnable {
    public void run() {
        System.out.println("Thread started");
    }
}

Thread thread = new Thread(new MyRunnable());
thread.start();

3. Using lambda expressions (Java 8+)

Thread thread = new Thread(() -> System.out.println("Thread started"));
thread.start();

4. Using ExecutorService to manage a thread pool

ExecutorService executor = Executors.newFixedThreadPool(2);
executor.submit(() -> System.out.println("Pool thread started"));
executor.shutdown();

Each of these methods allows creating and starting a thread, the choice depends on the task and preferences.
