Q1: What will be the output of the program?

class Base
{ 
    Base()
    {
        System.out.print('Base');
    }
} 
public class Alpha extends Base
{ 
    public static void main(String[] args)
    { 
        new Alpha(); /* Line 12 */
        new Base(); /* Line 13 */
    } 
}

ANS:A - Base

Option B is correct. It would be correct if the code had compiled, and the subclass Alpha had been saved in its own file. In this case Java supplies an implicit call from the sub-class constructor to the no-args constructor of the super-class therefore line 12 causes Base to be output. Line 13 also causes Base to be output. Option A is wrong. It would be correct if either the main class or the subclass had not been instantiated. Option C is wrong. The code compiles. Option D is wrong. There is output.
