[CODE}
class MyRunnable implements Runnable
{
public static void main(String[] args)
{
new Thread( new MyRunnable(2) ).start();
}
public void run(int n)
{
for(int i=0; i<n; i++)
{
System.out.println("Hello World");
}
}
}
[/CODE]
I tried running this code, but it shows a compile time error saying that MyRunnable should be declared Abstract.
But there is no Abstract method in class MyRunnable???
Please explain..

You are trying to instantiate MyRunnable with a constructor taking one argument and you haven't declared any constructor. By default you only have the default constructor taking no arguments.
Moreover you declare the run method taking one parameter and whereas the run method of the Runnable interface doesn't take any arguments. The compiler says that MyRunnable should be declared abstract because there is no method run() with no parameters...
