What Method Must be Implemented by All Threads

All tasks must implement the run() method, whether they are a subclass of Thread or implement theRunnable interface.

In Java, all threads must implement the run() method. The run() method is the entry point for the code that will be executed in a separate thread. It’s a part of the Runnable interface, and when you create a thread by implementing the Runnable interface or extending the Thread class, you must provide the implementation for the run() method.

Here’s an example of a simple Java program with a thread implementing the run() method:

java
class MyThread implements Runnable {
public void run() {
// Code to be executed in the separate thread
System.out.println("Thread is running");
}
}
public class Main {
public static void main(String[] args) {
// Creating a thread
Thread myThread = new Thread(new MyThread());

// Starting the thread
myThread.start();
}
}

In this example, the run() method in the MyThread class contains the code that will be executed when the thread is started. The Thread class is then used to create and start the thread.
