2. <em>A reference of type A can be treated as a reference of type B</em> - False

Base class or its objects are not related to their derived class (or its objects).

   public A() {

       a = 7;

   }

}

class B extends A {

   int b;

   public B() {

       b = 8;

   }

When an object of a derived class is declared, the constructor of base class is called before the constructor of derived class (is called).

3. <em>Both variables a and b are instance variables </em>- True.

Classes can have instance, or member, variables and methods.

4.<em> After the constructor for class B executes, the variable b will have the value 8</em> - True.
