GIGO: words unreadable aloud

Chapter 6, Exercise 1

Create two classes, A and B, with default constructors (empty argument lists) that announce themselves. Create a new class called C that inherits from A, and create a member of class B inside C. Do not create a constructor for C. Create an object of class C and observe the results.

package x;
class A { W.rn( "A constructor called" ); } 
class B { W.rn( "B constructor called" ); }
class C extends A { val obj_b = new B(); }
object c6x1 {
    def main ( args : Array[String] ) = {
        val obj_c = new C();
    }
}

Output

A constructor called
B constructor called
