Exercises

1. Create
   two classes,
   A
   and
   B,
   with default constructors (empty argument lists) that announce themselves.
   Inherit a new class called
   C
   from
   A,
   and create a member
   B
   inside
   C.
   Do not create a constructor for
   C.
   Create an object of class
   C
   and observe the results.
2. Modify
   Exercise 1 so that
   A
   and
   B
   have constructors with arguments instead of default constructors. Write a
   constructor for
   C
   and perform all initialization within
   C’s
   constructor.
3. Take
   the file
   Cartoon.java
   and comment out the constructor for the
   Cartoon
   class. Explain what happens.
4. Take
   the file
   Chess.java
   and comment out the constructor for the
   Chess
   class. Explain what happens.
