Hello

I am using the following code but it compiles fine but do not print "In Run" in console . Whats the reason behind this ?. Please help . Thanks in advance .

public class Tintin implements Runnable{
public static void main(String ...args) {
new Thread().start();
}

public Tintin() {
}

public void run() {
System.out.println("In Run");
}

}

new Thread().start()

You're not creating an instance of the Tintin class, but an instance of the Thread class.

You need to specify the object instance that you to run the thread on, do the following and it should work fine:

Job that is done is the thread class's run() which has nothing and neither has been overriden. To make your run execute you need to tell the thread to use your run() by passing the job instance.
