Write a java program which use of Runnable Interface.​

Introduction​

The Runnable Interface is one of the building blocks of thread programs in Java. It is a functional interface which can be implemented using a lambda expression or by creating a separate class. Java's Runnable Interface provides a thread system with a way to handle executable tasks. This allows developers to spawn multiple pieces of code, running in parallel, and have a single entry point and the ability to interact with those threads.

Code​

public class sample implements Runnable{
    @Override
    public void run(){
        System.out.println("Thread started");
        System.out.println("Current Thread: " +
        Thread.currentThread().getName());
    }

    public static void main(String[] args) {
        Thread t = new Thread(new sample(), "MyThread");
        t.start();
    }
}

Output​

Thread started
Current Thread: MyThread
Explanation

The above code uses the Runnable Interface to create a new thread which is labelled "MyThread". The sample run() method is then called to print a simple message to the console.
