Why does this code not has output?

Question

class MyThread extends Thread{
public void run (int i){
System.out.print("i");
}
}
class ThreadDemo{
public static void main(String [] args){
MyThread t = new MyThread();
t.start();
}
}

Answer 1

From what I recall, it is because the run method of the Runnable interface requires no arguments to be passed in. In your case, int i shouldn't be there as a parameter of the run method.

There maybe any another reason, as I'm not pretty sure about it. :\
