what is thread which are two ways to create thread in excution

 

A thread is a unit of execution within a program. It allows you to run multiple parts of your program concurrently. This can be useful for tasks that don't require the full attention of the processor, such as downloading a file in the background while the user continues to interact with the application.

There are two main ways to create threads in most programming languages:

Extending the Thread Class: This approach involves creating a subclass of the Thread class (or its equivalent depending on the language) and overriding the run method. The run method contains the code that the thread will execute. Here's a general outline:

public class MyThread extends Thread {

  @Override

  public void run() {

    // Your thread's code goes here

  }

}

Implementing the Runnable Interface: This approach involves creating a class that implements the Runnable interface (or its equivalent). The class must also define a run method. You then create a Thread object, passing the Runnable object as a constructor argument. Here's a general outline:

public class MyRunnable implements Runnable {

  @Override

  public void run() {

    // Your thread's code goes here

  }

}

public class Main {

  public static void main(String[] args) {

    MyRunnable runnable = new MyRunnable();

    Thread thread = new Thread(runnable);

    thread.start();

  }

}

Both approaches achieve the same result: creating a new thread that can run concurrently with the main program. However, there are some advantages to using the Runnable interface:

• More flexible: A class can implement multiple interfaces but can only extend one class. So, using Runnable allows your class to be more versatile.
• Separation of concerns: The run method can be defined in a separate class, making the code more organized.
• thread lift up before
