Abstract Classes and Methods in Java
Description
This lecture introduces the concept of abstract classes and methods in Java, focusing on polymorphism and link resolution. It explains how abstract methods are used to impose requirements on subclasses, using examples from object-oriented programming. The need for abstract methods is illustrated through scenarios where defining general methods at the superclass level is not feasible. The lecture also covers the syntax and implementation of abstract methods, emphasizing their role in ensuring consistent behavior across subclasses.
