Java program to create a thread by extending the Thread class

Java example to create a thread by extending the Thread class.
Submitted by Nidhi, on April 06, 2022

Problem Solution:

In this program, we will extend the Thread class and override the run() method. Here, we used the start() method to execute the thread. (Learn: Java Thread run() vs start() Methods)

Program/Source Code:

The source code to create a thread by extending the Thread class is given below. The given program is compiled and executed successfully.

// Java program to create a thread by extending 
// the Thread class

public class Main extends Thread {
  public static void main(String[] args) {
    Main thrd = new Main();

    thrd.start();

    System.out.println("Outside the thread");
  }

  public void run() {
    System.out.println("Thread Executed");
  }
}

Output:

Outside the thread
Thread Executed

Explanation:

In the above program, we created a class Main by extending the Thread class and overriding the run() method. The Main class also contains a method main(). The main() method is an entry point for the program. Here, we created the object of the Main class and used the start() method to execute the thread.
