Problem statement

In this program, we will create a class and implement the Runnable interface and override the run() method.

Java program to create a thread by implementing a Runnable interface

The source code to create a thread by implementing the Runnable interface is given below. The given program is compiled and executed successfully.

// Java program to create a thread by implementing
// Runnable interface

public class Main implements Runnable {
  public static void main(String[] args) {
    Main m = new Main();

    Thread thrd = new Thread(m);

    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 implementing the Runnable interface 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 objects of the Main class and bind with the Thread class. After that, we started the thread by calling the start() method of the Thread class.
