This week we will be covering inheritance. The first part shows how inheritance is specified in Java and what it means. Inheritance lets programmers similar object by specifying only the parts that differ.

This part of the lecture introduces UML, a visual language for describing object oriented programs. Here we cover only class diagrams that describe the relationships between classes.

The final part of the lecture covers polymorphism. Polymorphism lets classes share behaviors that the conceptually similar, but must be implemented differently. Polymorphism lets the programmer think of the behavior of an object without worrying about the implementation.
