Multiple Choice Question

Consider the following code:

class Super { static String ID = "SUPER"; }

class Sub extends Super{

static { System.out.print("In Sub"); }

}

public class Test{

public static void main(String[] args){

System.out.println(Sub.ID);

}

}

What will be the output when class Test is run?

E. None of the above.

Multiple Choice Question

Given:

abstract class Abstract1 {

  public abstract static void main(String[] args);

}

abstract class Concrete1 extends Abstract1{

  public static void main(String[] args) {

   System.out.println("I am an abstrsct class"); 

}

}

What will be the result is we compile and run Concrete1?

Select 1 option:

A. Class Abstract1 will not compile

B. Classes will compile, but will fail at runtime as Concrete1 is an abstract class

C. Class will compile, run and print "I am an abstract class"

D. Class will compile, run and print nothing

Given:

abstract class Abstract1 {

  public static void main(String[] args) {

}

abstract class Concrete1 extends Abstract1{
}

What will be the result is we compile and run Concrete1?

Select 1 option:

A. Class Abstract1 will not compile as abstract classes cannot have main method

B. Classes will compile, but will fail at runtime as Concrete1 does not have a main method

C. Class will compile, run and print "I am an abstract class"

D. Class will compile, run and print nothing
