Session O2: Inheritance

In this laboratory session, you will learn about inheritance, one of the key characteristics of object-oriented languages. The goals of this laboratory session are to

• examine selected issues in good software design, particularly code reuse;
• motivate and introduce inheritance; and
• investigate Java's primary inheritance mechanism.

Your instructor will tell you which of the experiments you are to perform.
