Kuidas saab Java's andmevoogude loomist realiseerida ja millised on nende erinevused?

In Java, creating data streams (streams) can be implemented in several ways:

1. Inheritance from the Thread class

   • Create a class that extends Thread and overrides the run() method.
   • Start the stream by calling start().

2. Implementation of the Runnable interface

   • Create a class that implements Runnable with the run() method.
   • Pass the object to the Thread constructor and start it.

3. Using ExecutorService

   • Allows managing a thread pool.
   • Useful for scalable applications.

4. Using Callable and Future

   • Allows obtaining a result from the thread.

Differences:

• Inheriting from Thread limits inheritance, as Java does not support multiple inheritance.
• Runnable is more flexible, allowing composition.
• ExecutorService simplifies thread management and their lifecycle.

Example with Runnable:

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

public class Main {
    public static void main(String[] args) {
        Thread thread = new Thread(new MyRunnable());
        thread.start();
    }
}
