Base()
{
System.out.print("Base");

What will be the output of the program?

System.out.print("Base");
}

Answer: Option B

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.
