Java OCA OCP Practice Question 3234

Question

What will be the output of the following program? 

class Base {//w w  w.j  av  a2s. c o  m
     public Base() {
             System.out.println("Base");
     }
}

class Derived extends Base {
     public Derived() {
             System.out.println("Derived");
     }
}

class DeriDerived extends Derived {
     public DeriDerived() {
             System.out.println("DeriDerived");
     }
}

class Test {
     public static void main(String []args) {
             Derived b = new DeriDerived();
     }
}

a)      Base/*from  w  w  w.ja v a  2  s .c  o  m*/
        Derived
        DeriDerived

b)      Derived
        DeriDerived

c)      DeriDerived
        Derived
        Base

d)      DeriDerived
        Derived



a)

Note

Whenever a class gets instantiated, the constructor of its base classes (the constructor of the root of the hierarchy gets executed first) gets invoked before the constructor of the instantiated class.
