Create New Thread Using Runnable Example

public class CreateThreadRunnableExample implements Runnable{

/*
* A class must implement run method to implement Runnable
* interface. Signature of the run method is,
*
* public void run()
*
* Code written inside run method will constite a new thread.
* New thread will end when run method returns.
*/
public void run(){

for(int i=0; i < 5; i++){
System.out.println("Child Thread : " + i);

public static void main(String[] args) {
                /*
* To create new thread, use
* Thread(Runnable thread, String threadName)
* constructor. */

Thread t = new Thread(new CreateThreadRunnableExample(), "My Thread");

/*
* To start a particular thread, use
* void start() method of Thread class.
* Please note that, after creation of a thread it will not start
* running until we call start method.
*/

t.start();
for(int i=0; i < 5; i++){

}
}

Output:

Main thread : 0
Child Thread : 0
Child Thread : 1
Main thread : 1
Main thread : 2
Child Thread : 2
Child Thread : 3
Main thread : 3
Main thread : 4
Child Thread : 4
Child thread finished!
Main thread finished!
