Threads - Programming

Q1:

What will be the output of the program? 
class MyThread extends Thread 
{
    public static void main(String [] args) 
    {
        MyThread t = new MyThread();
        Thread x = new Thread(t);
        x.start(); /* Line 7 */
    }
    public void run() 
    {
        for(int i = 0; i < 3; ++i) 
        {
            System.out.print(i + '..');
        }
    }
}

A Compilation fails.

B 1..2..3..

C 0..1..2..3..

D 0..1..2..

ANS:A - Compilation fails.

The thread MyThread will start and loop three times (from 0 to 2). Option A is incorrect because the Thread class implements the Runnable interface; therefore, in line 7, Thread can take an object of type Thread as an argument in the constructor. Option B and C are incorrect because the variable i in the for loop starts with a value of 0 and ends with a value of 2.
